  • 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.

  • 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

  • Good costume size up
Color: Light Blue Size: 9-10 Years
The costume is great but I had read a review to size up so I did. This is for my 7 year old daughter she is slim but tall. I bought the 9-10 and it was still barely big enough. Luckily it fits my 5 year old so I’ll just order a bigger one for her. Otherwise it’s very cute and soft besides the sizing I would recommend! ... show more

  • So comfy, I love it
Color: Pink/Red Size: Medium
I am 5ft3in and 145ish lbs I normally wear mediums and ordered a medium and it fit great! It is a little baggy and long on the limbs, but that’s how I prefer things (all shown in pics 1 pic I have it normal and the other to show the length). It is SUPER soft and seems to be fairly warm. I could definitely put some layers underneath for cold Halloween night if needed. I was extremely surprised and thrilled that it has pockets! It was a little wrinkly at delivery but I could truly care less! ... show more

  • 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.

  • Tall tween approved 👍
Color: Pink/Red Size: Medium
Fit tall tween great! We’ve had a few onesies from this brand and all have been great! Kept her warm and comfortable for Midwest trick or treating, which can get cold! Wish it had a tail!
