Horrible.  Horrible.  Horrible.  I'm not sure which bra the other reviewers wear that gives them all sorts of support and allows them to go from wearing 2+ bras while exercising to this 1 "awesome" bra...there's no way it was this bra.  I tried it on yesterday and did just a simple "jump test" and almost knocked myself out.  I was bouncing everywhere!!  I am a 3-bra-at-a-time kind of gal when I work out - - with this one I think I could maybe get away with wearing two...that's the only good thing I can say.  Very disappointed!  Back to the drawing board!
