  • Comfortable and cozy!
Color: Red/Yellow Size: Large
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. ... show more

  • Great costume
Color: Green/Blue Size: X-Large
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.

  • Super Soft Piglet Onesie – Perfect for Halloween & Disney
Color: Pink/Red Size: X-Small
This Piglet onesie is unbelievably soft and cozy. We got it for my daughter to wear to Oogie Boogie at Disneyland for Halloween, and it was perfect. The fabric is plush and comfortable, not itchy at all, and she stayed cozy the whole time. Such great quality and absolutely adorable.

  • Great quality!
Color: Light Blue Size: 5-6 Years
Great quality! Daughter absolutely loves this. She wears them as jammies now but used it initially for halloween costume. Very soft, warm. Size true to fit. Has room to wear layers underneath but it is really warm with out layers. I wash it a lot and it still looks new.

  • Super cute but size up
Color: Blue Size: Small
The onesie is very comfortable and I love how vibrant the colors are. I typically wear a size Small, but I felt that the torso length is a bit short, so it's very snug around the butt area. If you want a baggier feel, go one size up. The material isn't super thick, but it is warm.

  • Softest, coziest costume ever!!!!
Color: Blue Dot Size: XX-Large
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. ... show more
