Take this for what's worth. Being a man with Gynecomastia I have been wearing bra's for the last year pretty solid. I tried to look and use them guides. Here is my observation.
If your breast's are wide set, all bets are off as to cup size, just almost the same if you are fuller in the center and not so much on the outside.
According to my measurements.
Top of bust(armpit) 43.5"
Across Nipple 48"
Under Bust (strap would go) 40"
most bra guides put me in a 44 DD(F)
LOL... B.S.
It's more like a 40 C So, go off your strap measurement. As far as Cup size, if you eyeball it, buy a cheap one and see how it fits you. To me, you might be a D cup, just by looking at your picture.
