I finally got correctly sized and needed a 32D.  I had been wearing a 36B since highschool and never bothered to change it.  This bra gives me so much more support than the old one I'd been wearing that I almost can't believe it.  It's soft and seamless under my clothing, the straps stay on my shoulders without digging in and the band stays horizontal and does not ride up my back at all.  This is now the best fitting bra that I own and I'm very pleased with it.
