I 'm a 67 year old exercise specialist for several wonderful physical therapists.  When I changed careers from commercial insurance underwriting to pilates instructor specializing in rehab I also switched from under-wire to wire-free bras.  These are the most comfortable, most flattering bras I've found.  The price is reasonable.  I wash them in Woolite, zipped into little mesh bags on delicate and it's difficult to tell the year old from the new after a few washings.
