If you want a bit more shape or support to form a round bust. Cute cup will give you a lovely soft cleavage. Its an A or B cup but due to our underwire shape, try the next size up if you are a C Cup. The underwire design won't cut into the bust flesh under your arm and the shoulder straps are adjustable. The back strap is such a great return soft lycra, it can cover 2 sizes easily and still be nicely firm. Slightly padded cup.
