Maybe your kid wants to dress up like an 80s rock star. Maybe they're a hip lady bug, or a can-can dancer, or a high-school aged monster. If this is the case then just plain tights simply won't do (can you say boring?). Your kid will need some pretty unique stockings to finish off their outfit. And if you want unique, look no further than fishnet tights. Here we have our Kids Black Fishnet Stockings. They're 100 percent nylon with an elastic waistband and the 'fishnet' pattern. These will be perfect to layer under monster outfits, for flappers, bugs, or goth costumes. We're talking zombie cheerleaders, vampire princesses, or dark fairies. All would look better with black cross-hatching over the legs. Layer with other colored tights or leggings for a cool effect!

Super-Chill Sloth Sloths know how to hang. They're super-chill creatures who like to cozy up on a tree branch and gobble up some greens.

A Kiddo's Pet Name What do you like to call your little one? Sweetie? Sugar? Those are both pretty great options, but they are also pretty common. Delicious snacks are beloved because you just wanna eat them up! Adorable animal names are the next most common. Everything from Dove and Chunky Monkey all the way to Newt and even "My Little Honey Badger" for those particularly aggressive kiddos!  But you want your kid's nickname to be a bit more unique. Something that helps her know just how much they rock! Well, we'd like to introduce you to one of the very first adorable names... though it has been lost to time a bit! It's perfect, though. You're describing how little and cute your child is. You're also implying that she's pretty tough. (And, if you've noticed that your kiddo seems to slip into your bed or into trouble with ease, it's even more perfect!) For all of that fun, it is time to give a little give to your little Pebbles!  Design & Details Make sure everyone knows exactly who your little pebble is when you give your child this officially licensed Classic Pebbles costume for kids.

The Most Dangerous Creature of All Beware of the newest dinosaur at Jurassic World! It doesn't have the gnashing teeth and camouflage capacity of the Indominus Rex, the sharp claws and deadly hunting skills of the Indoraptor, or the sheer size of the Gigantosaurus, but it does have something even more powerful than any of these traits. It's just so cute! People have been known to want to give it whatever it desires, which makes it very dangerous indeed.  Product Details No animal at the famous dinosaur theme park has ever been as adorable as your child will be while wearing this officially licensed Infant Jurassic World T-Rex Hatchling Costume! The outfit includes a jumpsuit made of soft orange-brown fabric and printed with brown speckles on the sleeves, legs, and attached soft-sculpted tail. An white fabric eggshell accessory secures over the waist and upper legs, so that it looks as though your child is peeking out of a cracked egg. The matching hood fastens under the chin and is decorated with printed eyes, a soft-sculpted snout, and fabric dino teeth.  The Discovery of the Century  Scientists have long asked the question, "Could dinosaurs and humans co-exist in peace and harmony?" but until now, they've never had the opportunity to test any theories. Anyone watching this baby predator at a gathering would realize that people and dinos really can be friends, as long as the dinos are this little and cute. True, this guy might gum a few fingers at any costume party it attends, but it would do it in a non-lethal way. 

A Sloth's Fast Rise When did sloths become so popular? Was it due to the DMV sloths of Disney's Zootopia film? No, it must have been something earlier. Most sources point to 2012, when the internet seized a few sloth memes and shot them to pop culture fame. (If you haven't seen Kristen Bell freak out over a surprise sloth, well, it's worth watching!) No matter what started it, sloths are here to stay. Do you have a small sloth lover in your house? Then they will love moving in slow motion in this Kid's Bubble Sloth Costume! Product Details Sloths are very furry, so every piece of this costume is covered in super soft gray materials! The "bubble" part of this costume comes into play on the tunic, which has padding around the lower half to make it nice and round. The matching hooded headpiece has darker fabric around the eyes and for the nose, and a tiny smile sits just underneath the nose. Long claws made of white fabric curl out from the shoe covers and mittens. No need to worry about these pointies poking holes in anything! You'd...Better...Grab...This... Costume! You'd better grab this costume! Whether your child decides to do everything in slow motion or run around in glee, they will have a blast pretending to be a sloth. Climbing trees, eating leaves, and napping...what could be better? Let your child live like a sloth for a day—though they may race to get candy, regardless!
