As the title says, this is mainly to satiate my curiousity as I finally went out and brought the size the calculator suggested (36E) and with a demi cup the bra fits pretty perfectly. The bras are M&S demi cup bras with molded cups and underwire (I did try non-wired with no molded cup but I didn't like how they sat, I like how wires 'hold' my boobs almost).

I am curious though, since they only had the one 36E I also bought a 38DD as I thought that would be the sister size for my bras and my band airs on the higher end of 36 but I get gaping in the top of the cup that isn't the on the 36E.

I would appreciate thoughts on this?
