  • Cute and warm adult costume
Size: Large Color: Dinosaur
This was a hit, super fun and cute, great quality, soft and comfortable. It washed well and will be used again. Size was correct and didn’t notice any funky smell upon receiving.

  • Very cute, very good quality!
Size: Small Color: Raccoon
This is my mom’s account but I got this literally like the day before and it arrived on Halloween. Just in time, it’s good quality super, super soft. The only thing I didn’t like was the zipper across the back. I didn’t notice it in the picture my fault. But that’s just preference. But overall it was perfect, super cute, super warm, perfect size. Kept me warm while I was out at Six Flags. Durable and fun and didn’t smell. I still wash my items before wearing them though. ... show more

  • Comfy and warm.
Size: Medium Color: Dinosaur
Super cute, warm and fuzzy. Love the zipper in the rear and the free flow of the fit. Material is light and breathable. Bought a size L for my son who is about 67inches.

  • Love it
Size: Small Color: Dinosaur
I’m so happy I bought this. It was bought for halloweeen but I love it and basically live in it now at home. I like how soft it is. The zippers are good quality. The only issue I had with mine was that in the pocket when they sewer used the serger the fabric wasn’t lined up and left a hole in the left pocket. I only know what happened from sewing experience. It was fun and got the job done for what I originally needed. I felt very cute and had a great time in it at our community event. It’s thick and warm, doesn’t wrinkle easy and it’s sewn to last except for that one pocket. It’s pretty true to size as far as height goes though. I’m 4ft 10 and if it had been any smaller it would have been high waters but I appreciate that I didn’t drag the bottom of the feet to rip them and ruin them. Good quality product ... show more

  • Crazy Cozy Comfort Costime/Jammies
Size: Large Color: Bat
Super high quality, I wanted Halloween onesies for the family for fun and photos and this is such high quality and so warm! It even has pockets! I would advise to get a size larger as it does ride up with the wings a bit! They are fun and I still wear it as it is washable and very thick for the cold part of the year super comfortable and not see through at all! ... show more

  • This is great!
Size: Small Color: Dinosaur
This is fantastic! The design looks adorable and matches the picture. I did notice the white circles near the bottom were slightly misaligned, but it's not a significant problem. It doesn't have any unusual odors. The onesie fits true to size, is fun to wear, but arrived slightly wrinkled due to being vacuum-sealed. Overall this is adorable, cozy, clean,easy to wear, and so on. ... show more

  • Fun and warm
Size: Medium Color: Raccoon
Warm and comfortable. Fun onesie. Nice and thick, accurate sizing, no bad smells, I have washed it yet though so we'll see how it holds up.

  • High quality
Size: Large Color: Dinosaur
I bought this onesie for my daughter and she loves it. The material is so soft and thick. It is true to size. It’s so comfortable she wears it as pajamas but she also wore it for a Halloween costume. It’s a super fun, high quality onesie. I would definitely recommend
