Review: 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.
Review: IT HAS POCKETS! - SOO glad I bought this. It's hilarious! I'm 6' 0" guy about 158 lbs so I ordered a large. It fits perfect the sizing recommendations seem spot on. I will say that it is pretty baggy on me especially around the booty. That just adds to how funny it looks! It is soft and not itchy at all. I can imagine that it would get really sweaty if you dont layer right and I'll be taking this to work for Halloween so that is a concern for me specifically. On the other hand it will keep you warm! I wish they had the dino slippers that match that would be awesome. It has pockets too! But they aren't sewn in place on the inside so they flip back and forth. If you are handy with a needle, I'd say fixing it to the front so the pockets don't shift back and forth when you walk would be a good idea, just do it up nicely so it doesn't look like crap in the front. They are shallow as well, my S8 sticks out a bit. Well worth the price.

### ⭐⭐⭐⭐⭐ I love!

### ⭐⭐⭐⭐⭐ Good Onesie
*by A***N on January 13, 2026*

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.
