I hate wearing bras.  I've had a double mastectomy so there's no reason for me to wear one.  Don't need anything to hold them up...they stay up by themselves.  I've avoided bras at all cost. Until I found these.  Can't even tell you're wearing one! So
comfortable and soft.  Never had a problem with the bottom rolling up or sweat or anything.  And I'm very active.  This bra is so great after I got one I bought two more.  BEST BRA.  EVER!
