this bra is the only style i can really run, play soccer & zumba in without jiggle & pain.  so amazing!!  bra straps are always to long on me or too stretchy so they don't support a 36D for real activity. the adjustable straps make it fit perfectly! the classic racerback just doesn't cut it except for maybe yoga & bike riding; maybe if i wore 2, which is horribly uncomfortable. so glad i found you fiona bra!
