### ⭐⭐⭐⭐⭐ You’re on this page for a reason, just buy it
*by C***S on November 3, 2025*

Best Sebastian costume you’ll find probably. Great material, comfortable, XL was size appropriate.

### ⭐⭐⭐⭐⭐ Size up if you're between sizes!
*by Z***Z on November 10, 2025*

It was a little smaller than I expected, but I was kinda in between sizes anyways and went with the smaller option when I should've bought the bigger one to be safe lol. But it arrived fast, was comfortable and not scratchy for the second I had part of it on, and was pretty solid quality. It also comes with little covers on the Velcro so nothing gets stuck to it before it gets to you. Do recommend even tho I had to return it
