The Biggest Imagination Ever  It's not that you're extra hyper. It's just that you have more creativity than you know what to do with! Where others would see a boring metal bucket, you see the perfect thing to jump around in. Where friends see a regular featherbed, you see another fun thing to jump around on! (Honestly, most things can be used to jump with.) You have a sense of fun that's even bigger than a brown bear itself.  Product Details Fearlessly explore the forest in this exclusive, officially licensed Kid's Masha and the Bear Masha Halloween Costume! The outfit includes a white pullover shirt made of jersey knit material. Its sleeves are puffed at the shoulders and decorated with blue trim and buttons at the cuffs. The shirt looks just right under the sleeveles purple twill dress, which has a broad border of red, maroon, and white trim at its hemline. The included purple scarf matches the dress and can be tied as desired.   Play Time Just Started! When your animal friends are exhausted from trying to keep up with you, it's time to leave your yard, cross the tracks, and search the forest for a new individual who wants to play! The journey might involve eating a bunch of apples, chasing squirrels, and destroying a random house, but it doesn't matter how long it takes or how much you have to do along the way if it means making a best friend at the end. (Hopefully he sees it that way too!)   

Revelio Truth What was the first thing you ever learned about Slytherin? Probably that this Hogwarts house has produced its fair share of dark witches and wizards. But has anyone ever taken the time to let you know what's good about Slytherin house? There's a lot the ancient house can be proud of. When your Hogwarts student is heading off for the first year, it's a good idea to understand all you can about their potential house. Slytherin house is a family. A student who has been sorted and given the house colors and serpent badge, becomes part of that family—a Slytherin never leaves a fellow serpent behind. The students who don the emerald green and silver colors are some of the smartest and most ambitious students to learn at Hogwarts school. In fact, the most famous and learned of wizards, was a Slytherin—if a student is so lucky as to find themselves sorted into Slytherin, they're lucky enough to count themselves a member of the house that raised Merlin (yes, that Merlin). Magical legacies aside, the Slytherin common room is highly underrated. Students will find themselves enjoying a cool, luxuriously decorated room, with the only view of the Black Lake that can safely get a student up close and personal with the giant squid. While the reputation of Slytherin students might be tinged with a dark past, the reality of the noble house is quite different. And if the sorting hat announces your child the next member, you both should be proud! Product Details With this Deluxe Slytherin Robe, your child will look as cunning as Merlin himself. The exclusive robe is made with a deep-black fabric and lined with the emerald green of the Slytherin crest. Since resourceful Slytherins don't like having too many extras to fuss with, there's a full hood featured on this sleek robe, leaving no need to wear a separate hat. To keep this school robe in place, a simple button and loop fastener is stitched at the top of the neck. Completing the look is a Slytherin crest stitched to the front of the robe, ensuring that no Slytherin students will be caught without the powerful serpent on their side. Shameless Slytherin Get your Hogwarts students ready for their next adventure into the wizarding world with this stunning Slytherin robe. Like all Slytherins before them, they should take no shame in being part of the most misunderstood of Hogwarts' houses. They're going to have everything they need to show the world the true colors of a Slytherin student!

Power of the Monado In the world of Xenoblade Chronicles, some swords are just swords—and then there’s the Monado. It’s glowing, it’s mysterious, and it’s wielded by Shulk, the most unlikely hero to ever smack a Mechon in the face with a giant energy blade. If you’ve ever dreamed of jumping into battle with a cryptic British accent and a futuristic sword that occasionally grants visions, you’re going to want this replica in your hands. Product Details This officially licensed Xenoblade Monado Sword Replica is crafted with cosplay in mind. It’s built around a rigid plastic core and coated with a durable foam exterior that mimics the look of Shulk’s in-game weapon—without the risk of accidentally slicing your bookshelf in half. The red and silver paint application recreates the Monado’s distinctive design, including the glowing-style lines and signature circular center that screams “sci-fi magic.” It’s lightweight enough to carry around a con all day without turning your shoulder into mashed potatoes, and it’s safe enough for photoshoots, fan meetups, or that dramatic hallway walk to the kitchen when you want to feel like a champion of Bionis. Visions of Cosplay Glory Maybe you’re already assembling the full Shulk costume. Maybe this sword’s going straight on your game shelf as a display centerpiece. Or maybe—just maybe—you’re planning to crash a Halloween party and shout, “I’m really feeling it!” until someone finally gets the reference. Whatever your quest, this Monado replica helps bring your fandom to life with just the right mix of game-accurate style and safe, swingable flair. The Monado chose you. Don't leave it hanging.

A lot of ninjas just don't have a sense of personal style. For them, it's just all about wearing as much black as possible so no one can see them in the dark. That's all fine and good, but what about those ninjas out there who want to be super stealthy? They deserve an outfit that reflects their colorful style and their desire to practice the art of the shinobi... Introducing a new, totally exclusive, costume for girls that will combine their love of ninjutsu with their love of colors other than black! This Rainbow Ninja costume is a girl's outfit that features a black ninja jumpsuit with iridescent trim around the front and around the shoulders. A rainbow sequined dragon adorns the drape from the pink waist sash, to let her opponents know that she's a true master of the ninja arts. The iridescent wrist cuffs adds the final, subtle touch. It's a deadly, yet vibrant, way to show off her stealthy skills. Once your child has the full costume on, it's time to teach her all of your ultimate ninja techniques. Just make sure to grab one of our weapon kits, since she's going to need them if she wants to practice her new skills on Halloween night.

Party Power Activated Pizza party? Check. Nunchuck moves? Check. A wildly energetic sense of fun that cannot be contained? Triple check. If your kiddo’s the class clown with a heart of gold, then this Girl’s TMNT Michelangelo Costume Dress is the perfect fit. Inspired by Mikey’s totally tubular style from the 90s cartoon, it’s designed for maximum fun with a side of turtle power. Design & Details Made from soft polyester ponte and jersey knit fabrics, this green dress is easy to wear and even easier to love. It zips up the back and features a printed turtle shell and belt design on the front, complete with Mikey’s signature “M” belt buckle. The dress hits that sweet spot between costume and playwear—perfect for Halloween, school parties, or just dominating the living room in full turtle flair. The accessories really bring the shell-tastic energy. You’ll get an orange eye mask to channel Mikey’s mischievous spirit, along with matching knee pads and gloves that keep things coordinated and comfortable. And of course, it includes a plush turtle shell that attaches to the back for the full Teenage Mutant Ninja Turtles transformation. Officially licensed and ready to party, just like the original Michelangelo. Cowabunga, Cutie! This costume is built for laughs, movement, and plenty of “Booyakasha!” moments. If your little one is all about good vibes and high-fives, Michelangelo is the perfect turtle to rep. Get ready for dancing, spinning, and probably a few spontaneous pizza cravings—because being Mikey means living life to the funnest.

Go for Fearsome You're a T-Rex, the king of the dinosaurs, but you're also undeniably cute for a giant, fanged lizard. Woody says that you almost managed to scare him a time or two, but is he just being nice? It's hard to tell. But everyone seems to like your cuteness so much that they don't mind that you're not terrifying.  Product Details Transform into your favorite dinosaur when you wear your exclusive, officially licensed Toy Story Rex Jawesome Hat for Adults! Made of green polyester velour, the hat is printed with a scale pattern and has a layer of foam between its outer shell and inner lining to help it keep its shape. It's decorated with embroidered eyes, appliqued nostrils, and felt teeth. The character mouth serves as the view port.  Out of the Toy Box  Andy, Bonnie, and the rest of the gang agree: There's no dinosaur who's more fun than Rex! He's incredibly versatile because he can be either a hero or a villain during imaginative play, and he's always ready to lend a hand when a friend's in trouble. His hands (and arms) are pretty short, but it's the thought that counts. 

Ultra Violet Kids come in every kind. Some are social butterflies and others can be pretty shy. But every kid shines in their own way when they get closer to something they truly love. If you have a child who has a real passion for superheroes and animated films, we have something that will make her feel super! Our officially licensed Disney and Pixar Violet costume from The Incredibles is just the thing! Design & Details This Made By Us exclusive was inspired by the forcefield-creating older sister from everyone's favorite superhero family.

Deep Sea Celebration Have you ever stopped to think: How would a mermaid celebrate Halloween? No? Oh...it's just us, huh? Wait! Your little girl has pondered this question, too. Phew, we're not alone! Well, we think we finally have the answer—and yes, this means we are absolutely positive, without a shadow of a doubt, that mermaids are REAL—drumroll, please... ...this Girl's Skeleton Mermaid Costume is just how a gorgeous mermaid might ring in the spooky season. Pretty cool, right? We know! Skeletons are apparently a really common part of mermaid lore (according to a few translations that have been found in sunken ships), so it's no surprise that this costume takes on a shimmery skeletal style. But somehow, this little mergirl is still really beautiful—even without the colorful shimmer of her tail. So, if your little gal likes the idea of having a true mermaid's Halloween, this costume is the perfect mix of eerie and ethereal to help her celebrate just like her merfriends down deep! Product Details This costume is bound to bring out the dark side of your darling mermaid, but in a totally great way! Not only is this dress-up look eerily pretty, but it's also fun to wear. It's a fitted black velvet gown that flares at the hem with tulle, mimicking a tail. A cool, skeleton bone print adorns the front of the dress, while a tulle peplum adds even more flair at the hips. Sparkly straps add just a hint of elegance to this skeletal look—she is a mermaid after all! Add hair accessories, face paint, or even a black trick-or-treating bucket for a pulled together look that's totally how a mermaid would do Halloween up right! Spooky Tails to Tell  Now we know how cool a mermaid Halloween is, we really want to see it for ourselves. Do you think your girl could get us an invite? We've got a great idea for a skeleton dolphin costume, and we bet we'd come back with some amazing stories!   

This is an Infant T-Rex Costume.

A black cat has crossed your path! Is it bad luck? Or is it good luck? Well, that all depends. On where you live. On whether the cat walks from left to right or right to left or toward or away from you. Or if you’re at sea. Or on how superstitious you happen to be. But us? We’re more on the “good luck” side of black cats. The Egyptians thought black cats were gods. There’s even an official Black Cat Appreciation Day (August 17th, if you’re interested in celebrating). But none of that matters if it’s your little one in this Toddler Little Black Cat Costume. Then it can only mean one thing – lots of good luck and lots of smiles, too! In fact, all of your neighbors and friends will be eager to be in the path of your kitten. The costume is the cat’s meow, whether your child is wearing it when going out on the prowl on Halloween or scampering around the house any old day. It’s pure black faux fur and velour and so soft you won’t be able to help cuddling your little black cat. The jumpsuit zips up the back and has a black tail sewn on to swish behind every scamper. Mitts and booties have cute little appliqued paws, and the hood has little black ears on the top and stays on with an elastic band at the back and a Hook and Loop fastener tab closure under the chin. Now, purring and meowing are optional, but helpful if your black cat wants extra treats.

Mean and Green If you believe that horrible song about the Grinch, then you will miss the point of this wonderful story. He is mean and Grinchy because he is not a part of the town, not because it is just his natural state. If they had ever sought to include him, or if he had ever made it known that he wanted to be included, this whole thing could have been avoided! That wouldn’t be as good a movie, though, so we suppose it is best that things turned out as they did. Plus, it is hilarious to watch him slink around committing the most harmless robberies of all time! Product Details Finding the perfect way to finish off your Grinch costume is as easy as getting your hands on a pair of these Dr. Seuss Grinch Child Fur Pants! These perfect pants have all the movie-accurate colors and textures of the real Grinch, but without the greasy feeling and, if you believe the song, the abominable stench. You will love these warm and comfortable pants not just for their quality, but also for their comfort. We can’t promise that they will keep you warm at the summit of Mt. Krumpit, but they should do the trick anywhere else!

Not Such a Grinch after All "The Grinch is a terrible person before his heart grows three sizes!" you may argue. "He's mean! He's rude! He spies on the Whos all the time from his cold and frosty cave. He plots to steal all of their presents simply because he can't stand to see another person having fun. He gyps the Who-ville mice out of crumbs from pure spite. Why, he even takes the last can of Who-hash!" All of these things are definitely true, but we know for a fact that the Grinch couldn't have been all bad, even before his radical Christmas Day transformation. Why? Because he owned a dog! The love of a dog is proven to make even the grumpiest person more tolerable. If you saw the Grinch walking down the street by himself, you might cross by on the other side of the road, but if he had Max with him? Well, then you'd be asking the green meanie "What's this cutie's name??" Product Details Let your best pup be the sidekick to one of the most famous Christmas characters of all time with this exclusive How the Grinch Stole Christmas Max Dog Costume! The festive red collar has a little gold jingle bell sewn onto it to tinkle merrily while your four-legged friend is racing to return the Whos' presents. The antler that the Grinch tied to your dog's head is secured with a matching red elastic band.  Maybe Christmas, Perhaps, Means a Little Bit More We all know that the spirit of Christmas is more than just material things - but having an awesome costume doesn't hurt! Your pup will bring holiday cheer to everyone who sees her and she'll have a great time doing it. 

Grim Beaker They’re the unsung hero of the Dark Ages. Back when most people running away from sickness, the plague doctor would tend to the ill and wounded. Of course, they did look a little like the Grim Reaper mixed with some kind of evil bird… but that was only because modern era medical technology wasn’t available to them back in the day. They had to work with what they had, so that meant thick robes and bird masks. Well, we happen to think that the plague doctors of old have a pretty cool look, even if seeing one back in the Medieval times meant grim news. That’s why our costume designers went to work making this plus size plague doctor costume. Design & Details This plus size plague doctor costumes comes with everything you need to look like a doctor of the Dark Ages. It comes ith a black robe and a matching black smock collar. The belt has various pouches on it and a fastener in the back. The hood covers the head and the mask fits over the hood. The mask fits with an elastic band and is made out of molded vinyl and is designed to give you a long beak. The eyes have mesh openings for vision. The black hat has a wire brim and fits on your head above the mask. Just put the included gloves on and you’ll look ready to tend to the sick! (Special note: due to the manufacturing process, the mask may have a strange odor. Let it air out completely to reduce the odor.) Off to the Festival Of course, this plague doctor costume makes for an excellent choice during your next trip to the Renaissance festival, but it also works as a creepy costume for a medieval-themed costume party.

A Dino Nerd Kid's Dream Alright, let's talk about dinosaurs—because every kid, at some point, thinks they're a paleontologist. And now, thanks to this Kid's Tyrannosaurus Fossil Costume, your little one can skip straight to the "I found a fossil!" moment. This costume is like, "Hey, I'm a T-Rex, but also, I've been dead for millions of years!" It's perfect for that child who wants to be both terrifying and historically accurate—an underappreciated combo, if you ask us. Design & Details This isn't just any ol' costume—it's a soft, minky jumpsuit made from 100% polyester, so your kid will be comfortable while scaring the daylights out of people. The all-over black and white bone print? Oh yeah, that's fossil chic. The jumpsuit zips up the front to make it easy for any kid to make their transformation. The foam-backed tail is sewn in, because what's a T-Rex without its iconic tail? And let’s not forget the headpiece, complete with felt teeth that scream, "I may be extinct, but I still have my bite!” The sewn-in shoe covers are a nice touch, too—no need to worry about ruining the look with regular ol' sneakers. Roar Back in Time If your kid's the type who knows the difference between a triceratops and a stegosaurus (and corrects you on it), then this costume is the one. It's the perfect mix of educational and cool. Plus, when they wear this, they'll be the most talked-about fossil since… well, since the actual T-Rex.

Lid-Wearing Legend There are two kinds of toddlers: the ones who make messes, and the ones who make messes while proudly announcing it. The Toddler Trash Can Costume is here for the bold little whirlwind who’s been living that chaotic gremlin lifestyle since day one. Now they can finally dress like the walking, giggling disaster zone they’ve always aspired to be—shiny, silly, and shaped like the most iconic bin on the block. It’s silver. It’s padded. It’s shaped like municipal pride. And it turns your kid into a five-star Halloween photo waiting to happen. Design & Details The costume includes a foam-backed silver lamé tunic with quilted ridges to mimic the look of an old-school metal trash can. It’s structured but lightweight, and features clear adjustable shoulder straps to get just the right fit over your toddler’s clothes—no wrestling needed. The soft shape keeps things comfy, even when they’re running around at full candy-fueled speed. The foam-backed lid hat completes the look, with a built-in top handle and elastic loops that work with the included plastic tubing to keep the lid hovering right where it should. More importantly, it stays on surprisingly well (at least until your toddler decides to dramatically fling it off mid-performance). Peak Toddler Comedy This costume is tailor-made for tiny chaos agents who love attention, snacks, and possibly making trash-related sound effects while stomping around the house. It’s easy to wear, absurdly funny, and somehow manages to turn a literal garbage can into the most lovable costume in your neighborhood.

Those Delightful Dog Days When it comes to bringing both babes and pups into your home, you never really know what you're in for. You might expect a puppy to get home and want to play all the time but they'll end up wanting to constantly sleep and cuddle. And the doctor might tell you that your child will only sleep and eat for the first few months but you'll catch them flipping onto their back during tummy time at their third month. That's the one shared dependable thing about puppies and babies. They're both unpredictable. While your little one is small, you might as well celebrate your child's puppyish side. Celebrate the way they both chew on whatever is closest, the way they both need you near at all times, the way they always seem to be hungry. And while you might not want to celebrate the way they always make a mess, the days of the diaper won't last long so you might as well joke about it! Want to see spot crawl? This costume is the perfect option for your little nipper. It's bound to earn some "ooohs" and "awws" when you head out for walkies! Design & Details This little onesie is designed by our dog-loving creative team. The suit has spots throughout with a gold bone right under the red collar. It has a tail on the back, right under the hook and loop strips that go up the back. Hook and loop strips also secure the hem of inner legs to keep diaper changes easy. The look is topped off with a separate headpiece that had floppy ears and big puppy-dog eyes.  Let Sleeping Dogs Lie Trick-or-treating and Halloween festivities can be exhausting. Now that we think about it, just being a baby can be exhausting. That's why this soft puppy costume is a great costume for your little one. They can doze while all the revelers can admire the sweetest little Spot around!
