I usually wear 30f(65f) in japanese sizing. I needed a strapless, deep plunge bra for a particular outfit and took my chances with this one. Knowing it’s american sizing and how it’s strapless, i chose 32d, thinking i could just shorten the band and that that would give me the lift i need. Upon trying on the bra, it’s hard to show in photos, but the cup shape doesn’t suit my shape. The cups are curved too much at the top. The bra also fails to give me the lift and support i was hoping for. Disappointed.
