I love!
Celebrated alone this year so didn’t get a photo but I am so pleased with this! Compared to other costumes, this one is super spacious! To give you an idea just HOW spacious it is, I’m a big guy, I have a 40” waist and football player build. I also have a long torso and I am 6’2”. Y’all I originally had shorts and a polo on when I first tried this on. I fit into this easily with shorts a a polo on under the costume AND it fit with room to spare! I recommend you size down if you like a tighter fit. I quickly had to take the shorts and polo off since it got too hot fairly quickly. For context, I keep my ac at 70 when I am opening and closing the door constantly and I am perfectly comfortable. You could even get these as cute loungewear pajamas for yourself or someone else when it’s cold out. There are no “feet” attached though so keep that in mind if you get them for pajamas. You just need to have bunny slippers for your feet if they get cold. The material is on the thinner side and more like a think felt-ish material but still it’s very soft and keeps warm and very comfy! Note: I have not walked around trick-or-treating in this since I would get the strangest looks since I’m well over 21 so I’m not sure how the wearability is for outside use.

Would buy again
I am 5'4, 175lbs. Thicker in the hips. I ordered a small and it fit width wise but the height did not. I ordered a medium and it was perfect and comfy. My husband is 5'11, 180lbs. He tried medium, it went mid calf. Body part fit but Large was better for length. Definitely have to wear something underneath if going outside at night (I did not and was cold). Hood stayed on, nice baggyness. Nice colors

Cute costume
Great costume!! Fits ok just didn’t like the big baggy part where the legs are. But overall it fluffy and thick enough to keep me warm while out trick or treating with my son.

Dino onesie
Bought this for my autistic nephew, and he absolutely loves it! Good quality product

Okay and does the job, but I'd rather buy from official Kigurumi
I bought this dinosaur onesie to replace the one I had and because the official Kigurumi brand version of this was discontinued. I'm 5'1'' and the small version fits pretty well, and it was comfy and warm. The quality is kind of mediocre though. The mouth/snout part of the dinosaur is very flat and doesn't look great. There were also a lot of places where the thread was loose and or coming apart. Luckily there was enough threading that the onesie literally wasn't falling apart and it survived the wash, but it makes me wonder how long it'll survive. Honestly now I just miss my old Kigurumi version of this dinosaur, and I kinda wished I just bought another dinosaur or animal directly from them instead.

Good Onesie
This onesie fit me well and kept me warm throughout the evening. Although the material doesn’t necessarily feel like the best, it certainly doesn’t feel cheap either. The area of the costume near your groin is certainly a little loose (best way I can think to describe it) and it feels like you’re wearing a pouch. However, I got used to it pretty quickly and it didn’t interfere with me walking. Overall, I like the product and I would buy another one from this company if I needed a new one.

These are the coziest costumes/pjs. Bought for a family costume and would seriously do it again. Great for even plus size people. I am a size 24 and these fit with room to spare. LOVE
