Cozy and Cute
Highly recommend! Quality matches cost. The medium size fits great! I am 5'2" and weigh 130 pounds. I would not describe it as a slim fit though. It's roomy enough to wear leggings and a top underneath, which is what I wanted. The only zipper is in the front (vertical). Does not have a horizontal zipper in the back, which is ideal because I don't think a zipper in that area is functional or appropriate. Overall, very soft, cozy, and colorful! Perfect for the winter months.

It stands the test of time!
I bought the shark onesie almost 6 years ago, and it still holds up! Terrific quality! I decided to come back and give it a good review after being let down by other onesies I've purchased. This one sets the bar for me. Its material is thick and warm, and it is reasonably priced. Every other onesie I've purchased from different brands, has been more expensive, with thinner material, and cheaply made, even falling apart after the first wash. This one stands the test of time! The one complaint I have is that the back fin does not have any stiff material in it to make it stick out, like it the photos. It just hangs there. If you're the crafty type, it's easy enough to fix yourself. Even after that, I give this 5 stars, based on the superior quality to other brands.

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.

Pleasantly Surprised
This was my first time wearing a onesie since I was in grade school and I was pleased. They did not cheap out on the fabric or design so the quality was better than expected. I sized up to an XXL because I was afraid it would be too tight if I got my regular size (XL) but it was much bigger than I thought. So, I would recommend either getting your regular size or sizing down if you're in between sizes like myself. It's very soft and the material is thick so you will be kept warm in this.

So cute and comfy! Fits great!
Soooo cute and comfy! I love that it is a slimmer fit compared to other brands. I also like that they offer in a size xsmall. Material is not too heavy but perfect to keep you warm. Threw in the washing machine a couple of times and has held up great.

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.

Fits a little tight, but comfy!
Pretty nice, very warm. It does run a little small for American sizes. I wear a large shirt and 34x30 mens pants. I bought the large and it's a bit tight all around. If I sit it pulls, if I squat you better have your fingers crossed lol. But seems good otherwise! The dino head on the top is pretty floppy, but that was anticipated. The outside is fairly soft, and the comfort level of it is pretty good too. I am skeptical about washing it, however.

Es amplio y la tela es suave y calentita. La cola está muy arriba en la espalda y las orejas no se sostienen solas, pero es bonito

Great quality, accurate sizing and they have pockets!! My kids love them. They like that they are able to put some leggings and tops underneath too to keep warm for Halloween. They will definitely wear them to lounge around the house too.
