Perfect for a costume!
This was perfect for our Monsters inc family costume! My husband is a true 2x and that’s what we purchased and it fit perfectly! It was very comfortable, has shallow pockets , has a zipper in the butt area for easy access for the bathroom! The only down side was it was hot here this Halloween so the costume was very warm . This style was perfect it wasn’t 100% identical to the actual sully but worked for the price ! The one thing we didn’t know before purchasing was the buttons in the front . This didn’t affect the style and made it very easy for on and off . The hood was a little small for my husband but he does have a larger head . If needed we would purchase again !!!!

Love it!
Fits perfectly!!! Sooo cute I love it! I got it for my husband and fits him super well!! We love that it has a zipper by the bottom for bathroom uses cuz doing those buttons would be a hassle.

Just like the photo
This was cute just way to hot, once try on and model in the kitchen made me feel super hot. Material was nice and soft.

Cute but buttons don’t stay closed
3 stars because the buttons were not done well on the front, it came undone the entire time I wore it because the holes to hold the buttons are too big. It wasn’t too tight at all but had to wear a white undershirt because it wouldn’t stay buttoned.

Adorable
Adorable onesie costume. Face is the hat so won’t see if unless you bend your head down. Aside from that the tale and colors are great. Super comfy and not too warm. Will work perfect for Halloween family costume.

Review
The outfit arrived in a state of disrepair, with the zipper broken and the material not meeting my expectations. It was so flimsy that I couldn’t move around without worrying that it might tear apart even more.

My son fell in love with this Sulley onesie! Very durable material and super comfortable! The onesie is literally identical to Sulley. True to size fit.
