I purchased this bra based on all it's fantastic reviews. The truth is the bra is just okay. It certainly isn't the worse exercise bra I have put on, but its not the best either.  I am a 38F and I truly have a big bust. My boobs flops when I exercise and not only does it hurt but I am a bit self-conscious of the visuals. ;) This bra did not stop the flop. It did smash them in a bit to reduce it some.  The straps were comfortable as well as the overall comfort of the bra. I exercise 1 to 2 hours daily and I need a super reliable bra and this one just isn't it.  I won't purchase another one and my hunt continues.  If your exercise routine isn't going to be a medium to high impact you might find the bra great.  Yoga and pilates would be fine.  Jogging, fast walking, aerobics, cross-training... definitely not especially for those gals whose bust is larger.
