We don't know for sure that you've sat down and decided your costume either needs to be, essentially, straight from the screen or something that is guaranteed to stand out. You may be thinking something high-quality and familiar is what you want. Or perhaps you've come to the conclusion that familiar but unexpected is the vibe. Either way, our exclusive adult costume collection has your back!

How? You ask. It might sound too good to be true, but it isn't! Because we've made some awesome relationships with names like Disney, Universal Studios, and Fox. Now, we get to whip up character costumes at the same quality you've come to expect from us on all our Made By Us costumes.

On top of that, we offer vendor styles in exclusive sizes, so whether you feel most comfortable in a size XS or 6X you can dress confidently as Scooby Doo's Velma (and so many other beloved characters!)

Of course, you'll also find classics that aren't tied to pop culture moments. A Black Cat Costume, Fire Captain Costume Uniform, and Galactic Alien Women's Costume is just as much fun for dress-up as Jack Link's Sasquatch, Grease's Sandy, or The Little Mermaid's Ursula.

Part of that comes down to the thought our design team and buyers put into their choices. But in the end, it all starts with what you want. Quality, variety, and fit for characters that you've always dreamed of being or are clamoring to portray to make your kiddo's first trick-or-treat the very best!

And while we offer a few items in this collection that lean more toward one-time wear and playtime fun, you'll also see most pieces are made to last! So, if you're building a costume collection you can feel confident adding the super soft Grumpy Bear hooded onesie to the closet—and grabbing it for every cozy weekend is even better.

Or pick a favorite style and share it after wearing it. Typically crafted from a variety of poly-blend materials and thoughtfully detailed, they'll hold strong for a friend. You may even be able to keep your favorite style safe for your kid you're hoping will one day want to dress as Tiana like you did years before.

From your dream character costume to the classic Halloween witch, our exclusive costume collection is here to ensure you find the style and quality you crave! Shop officially licensed costume dresses for Disney Princesses, 1980s movie essentials, even anime outfits when you dive in today!
