I have a very broad chest and shoulders, and wide-set breasts to match. I don't fill out a D cup, but most 40C bras are apparently built on the assumption that the high band length is all due to back fat, and so smash the cups in too close. This bra and also the Bali 3425 are the best I've ever found for my shape. I could honestly do with another inch in band length, but no one's ever come closer to getting it right.
If I'd known my "right size" (which Bali doesn't make in this bra)....sigh...I love the style, but the size it is means I'm pulling the back down and adjusting the straps constantly and all day. And it's still not comfortable for me, but that might be due to the constant fighting with it trying to make it so. The center gore doesn't tack, but where the cup starts at the side is maybe the one thing that does work for me, since I'm wide root and equally full all over (not fob or fot but somewhere in between...?)
