I wear a 38DDD and have literally NEVER owned a sports bra that simulataneously fit properly and offered adequate support.  Until, that is, I tried this one.  I bought three Glamorise sports bras at the same time, and while I liked them all, this one is my favorite.  It's comfortable and supportive (no bounce, even when running) and the fit is perfect. I find that the band is slightly more snug (although still not too tight) than most of my others sized 38, but I think that's part of why it's so supportive.  Even as it stretches out while I'm moving around, the band continues to fit snugly.
