This is my favorite workout bra ever!!  I'm really big busted (44 C) and did not think this would work, but I was willing to give it a try and I'm glad I did!  FYI....I'm not a little skinny chick either -- 5'1" 168lbs

I ordered it to wear under tank tops.  In the past I have tried different bras and nothing ever fits comfortable and most the time they are way to tight or small.....not this one!  It is kind of difficult to get on - I pulled it over my head and then have to work the big jugs in the holder :-)  but once everything was in place it was comfortable.  The back doesn't dig in anywhere and everything stays in place.  Seems to be very breathable in the heat too.....I wasn't sweating anymore than I would have with a regular bra.
