I have always just gone in a tried on til I find one that fits. I have found soo many brands differ in their cups sizes that it really doesn't matter how much math you do it all comes down to style and fit. I know what style I like (balconette)and I have shopped til I have found that style. I have low slung boobs naturally so having a shelf like bra brings them up and out, not smashed inward and toward my armpits like some I have tried. I have really close cleavage naturally and the balconette seem to seperate it some. I also love the upper pole look and that style seems to accentuate it better. It just seems like if I push my cleavage together it makes me look like I have a uniboob.
I have found a specialty store here where I live and they bring the bras in the room, help you with the straps and adjust the cups. You never see them on racks, they have them in drawers in the back room like its some kind of secret. There is no comparison to the European bras, its the fit and the quality that I fell in love with not the store, I was SOLD. They are VERY expensive though...so I only own a handful.
Have you tried any of the Olga bras? I have one style that I do like. I bought a 38 DD since I needed a larger cup and they don't go any higher than a DD. The cups are VERY stretchy so it will accomodate larger boobs. I have found the band runs a little small on that style too. Lane Bryant also has ALOT of nice bras...any luck there?
Good Luck with your bra hunting journey. There is NOTHING like a good fitting bra.
