    • Fun and comfortable Hedgehog onesie! Fun and comfortable Hedgehog onesie!
Size: Large Color: Hedgehog
Review Image by Amazon Customer
Review Image by Amazon Customer
I am 5'9" and 200 lbs, and the Large fits me very well overall. I did find it to be a little tight in the shoulders, but that is to be expected with a unisex cut. The fabric is a standout feature, with a textured, scaly look rather than a flat print. It's very soft and feels great to wear around the house. The details in the hood are really well done and give an awesome 3D hedgehog effect. The light-colored chest panel provides a nice contrast that makes the design pop. Plus, the elastic cuffs at the wrists and ankles are high quality and help keep the onesie in place while you walk. ... show more

    • Warm and cozy in here! 🦌
Size: Large Color: Coffee Reindeer
The holidays haven't arrived just yet. We're still a ways away but it's good knowing, ahead of time, that I'll be enjoying wearing a warm and cozy onesie. Aside from being the warmest onesie I ever owned, it's adorable. And I bought one for my daughter too. We're going to look jolly while listening to music and decorating for the holidays. ... show more

    • Fun Halloween Costume
Size: X-Large Color: Dinosaur
This onesie is very comfortable. It fits well and isn't difficult to clean or maintain. The fabric used for the fur is a bit annoying, as it catches and sticks onto clothing easily, almost like it is shedding in a way. The pockets are very convenient, but they are not very deep and can't hold too much. All in all, it is a comfortable onesie that's perfect for a quick Halloween costume. I do think it's better work with some underclothes. ... show more

    • Great Product
Size: Small Color: Pink Pig
This is cute. It worked great for my daughters Halloween costume, and it is still holding up and I'm writing this in February. It has been washed multiple times and it's not peeling or shrinking or loosing color. It's holding up great! My daughter uses it for her pajamas. It is really cute and a great price considering we've got a lot of use out of it. My daughter loves it because it is warm and cozy. ... show more

    • Soft and warm!
Size: Large Color: Grey Koala
This was a fun last minute purchase for a Halloween costume. It was delivered quickly. It fit well and according to the size chart. It is very soft and comfy! I also wore this during the recent snow storm and it kept me nice and warm. I am glad I purchased this.

    • Great quality! Love it!
These are so soft and comfortable! Fit a little small, but not too bad. Maybe I was expecting a looser fit than I have. I wear a small and ordered a small and now I am a shapely little frog. Nice quality fabric that washes well, and should last a long time!

    • SO COMFORTABLE AND FUN
My daughter absolutely loves this! It's soft, comfortable and warm! It's so fun for her to wear. She takes it every time she has a sleepover with friends.

    • Hammer part flops over, hard to tell what the costume is
Size: Large Color: Hammerhead Shark
This suit is hilarious. It’s comfy, fits well, but I wish the hammerhead part actually stood up. It flops over so it’s hard to tell what it actually is.
