I am a 34D (implants) and have had a slight issue with movement in one of my breasts which is causing friction when I run or play soccer.  My surgeon recommened the Enell bra.  I ended up buying a couple of them, but I found that they were so constricting that they ended up making the issue worse.  Not to mention they give granny panties a run for their money!  So, I came upon the reviews for this bra and decided to take a risk and it paid off.  I love this sports bra.  It keeps my breasts in place without feeling like I am being squeezed.  This is by far the best sports bra I have ever owned.  My only negative comment is that the lower band seems to run a little big. I decided to order 2 additional bras, but went down a size because of this.  I will update as soon as I receive them.  This bra is absolutely worth the money (and it is cheaper than the Enell)!
