Customer Reviews
Good price on a Witch costume
I was looking for a decent Witch costume for Halloween but didn't want to spend too much. Costumes.com had a pretty good sale going on. I managed to get one for about 30% off, which felt like a real win. Shipping was free too since my order was over fifty bucks. It wasn't the fanciest thing ever, but for the price, it was totally worth it. Came quick enough.
Decent costume, quick shipping
I ordered a Star Wars costume, specifically a Darth Vader one, for a themed party. The quality was better than I expected for the price, pretty solid. It arrived a few days earlier than the tracking said, which was a nice surprise. My only small complaint is the mask was a bit flimsy and kept fogging up when I wore it. Otherwise, the overall experience was positive, and I'd probably buy from them again for future costume needs.
Princess costume experience
My daughter wanted a Princess costume for her birthday party. I found a nice one on Costumes.com. The ordering process was straightforward, I just added it to the cart and checked out. Shipping took about 5 business days, which was fine, it got here with plenty of time before the party. The costume itself was a decent quality for a kids' item, not super high-end but definitely held up to a day of running around. I didn't need to contact support, so can't speak to that. She loved it, and it fit true to size based on their chart. Everything was pretty much as expected, no big surprises.
Got my Ninja costume fast
Needed a Ninja costume for a party last minute. Found one on Costumes.com. It shipped out super fast, got here in like 3 days, which was awesome. The costume was exactly what I needed. Easy peasy.

Share tips, ask questions & help fellow shoppers save more
Are their pet costume sizes accurate? My pug is kind of a weird shape so I wanna make sure it'll fit him.
I'm looking at a couple of licensed Marvel costumes, but I heard some places sell knock-offs. Are the ones on Costumes.com legit?
If I buy a costume now for Halloween, can I still return it *after* Halloween if something goes wrong or I don't use it?
Does Costumes.com do that first-time buyer discount thing? Or like, a newsletter sign-up code?
I'm trying to use two different promo codes, one for free shipping and one for a percentage off. Is that even possible?
