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.

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.

Complete waste of money! Way too small and zipper was broken upon arrival.
I ordered this costume in time for Halloween as my daughter is going to dress up as Boo, my pregnant wife as Mike Wazowski, and me as Sully. Now this idea is ruined as the costume arrived and is completely useless to me. I am 5'9" and bought the large as the product description said that a large would suffice someone at 69 inches. The rear of the costume also has a zipper that zips from hip to hip. Before I even put the costume on I tried to zip the rear closed, only to find the zipper was broken already. Broken on arrival. When I pay $40 for a costume I realize I'm not getting top of the line, but I expect it to be functional for at least one time use. I will be expecting a full refund on this product.

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.
