I am not big chested and never have been but I recently lost weight and with skin loose and less fat in my chest than ever, I had to go down a bra size. Tried this one because description indicated lift and I needed all the help I could get to lift up the sag and get what I do have into the bra. Fit is especially good looking under tee-shirts and sweaters.  I love this one and it is comfortable too.  I would buy this again.
