This really is a fantastic purchase for any lady who loves to exercise but needs the extra support. The sizing is true to your normal bra size (although I did go to my local running store to try one on first). It really does do the job.  I felt so comfortable the first time I wore it, I ran & ran & ran... then regretted it the next day when my hip complained!! This bra was recommended on a triathlon website/forum I use and it got great reviews there too.  Please take care to follow the washing instructions - it makes all the difference over time.
