I would like to say first that I'm a 38DDD and I have literally never had a sports bra fit me, but this one does!  It is extremely comfortable, covers my chest well, and is supportive.  HOWEVER, it gives me a pointed shape. I haven't read any other reviews saying they  had this problem, so maybe I'm just oddly shaped.  I'm still deciding if I'm going to keep it or not.  I feel self conscious enough at the gym without cone boobs...other than that, it is an amazing fit.  So still give it a shot.

--Update--
I've been using it for a few months now, and it is just as supportive as the day I bought it.  When you're big chested, you tend to wear a regular bra under your sports bra, so the "cone" shape isn't really a problem anymore.
