I imagine this would fit any bust size, but for larger sizes (I am 34DD) it does not have the extra part that goes around the wait, but merely just covers the bust.
I am giving this 3 stars because the nude color and white color are see through. This may only be because of my larger size, and having to stretch it, but it still should not be see through at any point, as the primary purpose for a bandeau is to cover up a bra or go bra less without it being see through. The black was fine.
Still going to keep them and give three stars because it was a good price and still fit, I just have to be extra careful with the nude and white ones.
