I bought this bra for my post-pregnancy workouts while I was still heavy-chested because still breastfeeding.  Other bras just couldn't keep the big working girls in line and ones that were small enough to keep them still would give me plugged ducts.  This bra was a dream and the best bra I've had in my life to date.  I never had to think about jiggling or bouncing or discomfort.  The fit was true and as my chest got smaller I was able to make the bra still work for me by cinching up the straps.  It's not designed to be a nursing bra but it was convenient for that purpose because of the velcro straps.  I have worn it every day for about a year for high-impact aerobic workouts - thousands of jumping jacks, hundreds of burpees, lots of jumping - never a single problem.  It has worn and washed well - no curling or warping or fading.  Yay!
