Love this costume!! It fits great (I am 5'10" ~200lbs guy) and the pockets are a real bonus. The only thing to consider, you gotta take it all off when nature calls. Otherwise, if you want a dinosaur costume that is fun and easy to put on etc. this is what you are looking for. One more caveat, don't wear it on a warm day, it is felted and man, it will keep you warm! Otherwise, it's comfortable, looks great and has held up through multiple wears (was "Dino" for a friends recent Halloween family portrait) and is a good value.

Used this as a halloween costume. Kept me warm, pockets came in handy, and it seems like it will withstand multiple wears. I ordered a Meduim but being 5'11" it is a little small: a large would be great.

Last minute buy for trick or treating with the kids! I’m 5’4”, 148lbs, Size 8 jeans, 36C. Purchased a medium. It’s unbelievably comfortable! Perfect purchase. Lots of room. Might not be warm enough in the cold weather, BUT with a long sleeve shirt underneath and thick socks. You gold.

Really nice costume/onesie! I had to return the first one I ordered because it ran smaller than my son wanted, but the medium fit him perfectly. The material is soft and lightweight — not too heavy, which is great for wearing indoors or to school events. I haven’t washed it yet, but will update when I do. It’s super cute and fun for a 13-year-old Halloween costume, and the quality is surprisingly good for the price. Definitely a win! Comfortable, cute, and teen-approved!

Awesome! Slightly hot inside even though it’s very cold outside. Very warm and comfortable! The Joey plushie that came with it was very flat; seems like it had no stuffing inside.

I am 5'7 125lbs and wearing a size Large. I got a medium too just in case but tried the large on first and its def the right size. medium would've been too tight and probably shorter on my ankles. Im standing on my tippy toes to show my ankles. it comes down far enough and fits well around my shoulders and waist. I wouldn't say its great quality but the colors are exactly as pictured. it came vacuum sealed so its suuuuuper wrinkly and the head is a bit sad... the antenna is supposed to stick up buuuut... yeah kind of ruins the angler fish vibe. I’m returning it :/ its not a thick material so its not super warm but its probably polyester so it'd keep your body heat in. no smell. its not very soft, just kind of costumey.

I love this, and I’m so glad I ordered it! It’s warm and comfortable. The color is just amazing. I have washed it multiple times with not wrinkles or strings. It washes amazing, but I do wash it by itself just to protect it a little more. The price is awesome, and I would definitely buy it again.

My 5’7” daughter loved wearing this costume. She wore to several Halloween parties and even to school for dress up!
