I am a 34-36D and I have a really hard time finding sports bras that are supportive.  I do a lot of high impact exercise that involves jumping and it is so hard to find a bra that keeps my boobs from bouncing everywhere!  The bras that are effective squeeze everything in, are uncomfortable, and look really bad. This bra is amazing!  Since I read in some reviews that it runs small, I ordered a 36D.  It fits perfectly!  There is almost no bouncing, it is very supportive, and looks great! My boobs look like they do in a regular bra.  All of my exercise clothes look better with it on.  I just ordered another one because I am never going to use another sports bra again!  I highly recommend this bra to anyone who has been frustrated by sports bras in the past.
