Of course, front zip bras for the endowed have their own problems (like requiring 4 hands to install). I don't have an answer but then I'm not a engineer.
It's a dilemma. I was a 36D/DD for a long time, I know where you're coming from. Here's the problem though. If you make a pull-over only bra with a band that stretches enough to get over the sheer mass of a D or DD chest, then the band becomes too big to really lend enough support to the garment. To compensate for that CW-X has a really nice racerback that has a single flat hook/loop on the band. I've owned and extensively wore the CW-X and it's a great bra. If you click into this and look at the alternate photos, you can see the back: http://www.teamestrogen.com/prodCW_165102.html As a bonus, CW-X just started making this in a 32D, which is a really hard size to find. ( FYI - my written review on that bra is a few years old. I'm wearing a 32C now and have an entirely different problem. 32Cs & especially 32Ds can be hard to find, though there's lots of choice in 34 C & Ds.)
