It’s comfortable, fits great…
I love the costume. It fits great. Im 5’11” female, 185 pounds, I purchased the XL and it fits in the length (below my ankle), the sleeves are really long (meeting at my hand) room in the belly area, but not too much, it fits perfect except my head may not be big enough for the hood. The reason for the 3 stars is because there is a light red stain in the upper right corner of the costume. It’s really light and most people won’t be able to see it when it’s worn, but it’s the thought of it being there. I only washed (in cold water) the costume once to get all the wrinkles out because when it arrived, it came in a vacuumed bag and was extremely wrinkled. Of course I always wash clothes before wearing for sanitary purposes. So disappointed of the stain for such a higher priced item. Hopefully customer service can help. See video attached. Even though it has a stain, I would highly recommend this costume.UPDATE - I originally rated this item 3 stars, but I am updating it to 5 stars, as their customer service took care of the problem and sent out a replacement (free of charge). New costume worked perfectly. Fit well and kept me warm the entire night, even though it was 36 degrees halloween night!! 😊

Always get my Halloween costumes from Funziez
Takes some trial and error for different costumes, but overall we like this brand. I've had the bear costume for a few Halloweens now and it runs big and roomy. The skeleton costume, new this year, runs true to size but kinda small at the same time. I would always rather have more room than things feeling tight in places. I look a bit funny in the bear costume because I'm short and the legs are lowly arched at the knee/calf area. But it's comfortable so I don't care. It also perfectly matched a separate kid's bear costume for my child. I look fine in the skeleton costume but the placement of the bone prints needs to be shifted down some. The pelvic bones are over my abdomen area. And when I sit down, that's when I notice a bit of the length and crotch area feeling tighter than when standing. To some that might like a "duh" statement but it's not. A properly fitted piece of clothing shouldn't feel like that when you change position, and going up a size wasn't available. The fabric in the skeleton costume just doesn't stretch or give at all, so be careful of ripping if you have a long torso or just have more padding in the rump area. The bear costume is soft, furry and was designed to be more baggy so definitely comfortable and while it is mildly breathable you will sweat because it's just alot of faux fur to wear. The skeleton costume is thinner, but feels more like felt and you will also sweat in it because it isn't breathable fabric. Zippers on both costumes work well, seem durable. I've worn the bear costume for three years in a row and always get compliments but the skeleton costume is new so we'll see how it holds up. Also wish it glowed in the dark.

XL fits 6'4" guy well, well made too
Very good especially for the price! Not too thick but won’t rip either it seems. I'm 6'4" and the XL fits me well height wise, and width doesn't matter since it's a onesie. It would fit someone up to 250lbs probably, I'm around 170 and it's floppy but in a good way. Doesn't hang off me.

Black fuzz?
It had black fuzz all over the legs had to pick them off. I got size XL it fit perfectly with extra room left. The head part is to big it covers my face. Materials are comfortable and warm perfect for autumn season.

Cute
Bought as a Halloween costume. So cute! Received lots of compliments. The sleeves were a little long but did not bother me. It kept me warm on the cold Halloween night. It was soft and came with a cute little chicken that could come in and out of its pocket. It was a little wrinkled when it arrived but after washing and drying it was fine. I did not fully dry the onesie in fear that it would shrink.

Served its purpose well for Halloween
Definitely served its purpose for Halloween dressing up as King Julien from Madagascar (yes, I even put the top of a pineapple on my head). It's soft and comfortable, at least before the first wash. I used it the one time and haven't found a use for it again.
