I wore this dress to see Usher in Vegas, received so many looks and compliments. Order your size and if you are busty I was able to wear without a bra and was fine. I’m usually 16/18 and a 44 DD/DDD. I could’ve gotten a 2X but I don’t think it would have held my boobs in place and has me as secure. Shapewear isn’t necessarily needed if you get your size.
