I'm not super big-chested (36 C), but the straps on this style that go across the top of my breasts seemed to push my boobs down in a way I didn't care for.  Next time, I would go for a style with thinner straps as well.  The criss-cross pattern at the bottom seems to disappear as the straps are too thick and close together.  Otherwise, the fit was fine and easy to adjust the straps.  Material was decent, too.
