I had a mastectomy 17 years ago and now have a saline implant.  Because of this and the aging process, my breasts are quite different from each other.  I need a bra that is both forgiving of the differences and show me to be symetrical.  This bra does the trick.  I have been buying this bra for years and my fear is that one day they will stop making it.  BTW, I use it for sports and find it to be extremely supportive.  I know of what I speak -- I am a 36D.  The fit is spot on with the size charts.  But I never will use it in the racer back format as it is very uncomfortable.  But it is not needed so voila, perfection as is.
