## Description

Product Description

Review: Comfortable and cozy! - I used to own a similar onesie bought at a large discount retailer, the quality of this onesie is definitely superior. It is thin but warm. I fit just right, I got a large and I am 5'2" and about 185 pounds. My husband got a Tiger one Medium size, his build is similar and it fit too. I think either Medium or large could have fit. The wrinkles went away in about an hour of having it on. The design is perfect and it is just stretchy enough to feel snug but not tight. The fabric is also soft in the inside, so it felt really good. We wore them to a big party and got a bit hot with all the people but at home it feels just right for a winter night. I just like lounging in these things and this was a good purchase.
Review: Great costume - Great halloween costume. Super soft and comfy, and surprisingly warm. It is not super heavy, but it did come with a smell that needed to be washed out. Got it for a group costume and it fit perfectly and looked super nice compared to a lot of the other ones I found online.

### ⭐⭐⭐⭐⭐ Softest, coziest costume ever!!!!
*by M***Y on October 11, 2025*

First of all, this arrived with 24 hours of ordering which is amazing. Second, it is SO SOFT! On the inside and out. This is the coziest costume ever. I bought a 2XL for my partner because he’s 6’ and I wanted to make sure it was long enough and roomy (not too snug), and the size is perfect. We’re gonna be Boo and Sully for Halloween, and while leggings and an oversized t-shirt are comfy, I’m honestly jealous of this costume cause it’s so freaking cozy! Perfect for sitting out on a chilly night handing out candy to the kiddos. I told him, next year we’re both getting these kinds of costumes because who doesn’t want to feel like they’re wrapped in a blanket all night?! Maybe we’ll be Pooh Bear characters, idk. But I know I’ll be buying again! No pic cause he’s 👉shy👈 lol, you’ll just have to trust me. It’s sooo good. Buy this.
