The underthings are useless. I used a bodysuit with shorts from amazon in a rust color and it works perfectly. The fabric is heavy and beautiful but you have to be delicate with it. The beads are secured well but if you tug, they will fall. The dress is long on me, but I'm 5'4". I would wear 4" heels to not drag. It's got plenty of give and I usually wear a size 2 (26). It gives me a lot of room in the back, so if you have a butt, you should be good. I don't really have much on top or on bottom lol so it's more slimming.
