Review: Great costume - Cute and comfortable. Matched my dog perfectly.
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.

### ⭐⭐⭐⭐ Would buy again
*by D***H on November 1, 2025*

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
