Comfy, cute, good quailty
I purchased this outfit for my daughter for Halloween as a backup because our other purchase never arrived. It was a great choice! The pajamas fit just right, were comfortable, functional, high quality, and just the right length.

Soft, cozy, and cute!
Bought to be a costume for my 7 year old and was very impressed with the quality. Now that Halloween is over, she wears them as pajamas and absolutely loves them!

Cozy, fun, and perfect for lounging or parties!
This onesie is super soft and warm, made with high-quality flannel that feels great on the skin. The loose fit makes it really comfortable to wear around the house, and the zipper makes it easy to slip on and off. I love the fun design—it’s perfect for Halloween, themed parties, or just cozy nights in. It even has pockets, which is a huge plus! Definitely a great buy if you want something comfy and playful.

Size down one from your size, but good product overall!
Overall, it’s alright. It’s definitely fun. Zipper is good and functional (doesn’t get caught). It’s easy to use and a decent material, in between a thick and thin. It’s cute but a little awkward when worn although that doesn’t really change that it’s really comfortable to wear. I would recommend sizing down one from your true size.

Soft and cozy
This zip-up costume is absolutely adorable! The material is super soft and cozy, my child loved it so much they even wore it as pajamas for a few nights before Halloween. It’s comfy enough for sleeping and perfect for trick-or-treating. I’d recommend sizing up if you want a looser, baggier fit. Overall, great quality and so cute in person!

Warm
This costume fit perfectly based on the size chart. It was a cold Halloween this year but this kept me nice and warm the entire time we were out trick and treating! I was surprised by the pockets. It came in handy when the kids handed me things like usual to carry. It even fit my phone as well so they weren’t shallow or useless! It was so comfortable that this may now become my costume every year.

Fits my toddler, but excess thread everywhere!!
It has a lot of thread pieces hanging and it looks to be pen ink on it?! Other than the pen ink and threads everywhere, it is such a cute costume my daughter loves it. It’s soft and will keep her warm. My daughter is 3 yrs old & is tall for her age, and skinny. She is usually a size 5t, and the 4t-5t size fits her perfectly.

Warm
These are much warmer than I expected. I buy onesies to sleep in during the very cold months. I got too warm in these, which is a first. Seems like it made really well and definitely thick.

Bought the XL. I’m 52” roughly 200 pounds. Fits well with a bit of room. Wanted something loose and baggy for Halloween as I will be roughly 20 weeks pregnant. Has a zipper. Wouldn’t say it’s overly thick so if your live in a particular cold climate you may want to wear leggings and a long sleeve underneath

There was a hole in the sleeve. My son was very disappointed
