I got my order for this item today and I immediately tried it on without a bra to see how well everything will hold because it's for my costume and GIRL! As a natural big chest girly who boobs DO NOT sit up, it'll held them nicely and they were covered up. I will say im thick so although it was long enough in the front, there is a bit of cheek action in the back, like the end of my butt is out.
