I ordered this in a 48D, which in some other styles & brands I am able to wear with no problem. This bra, though well constructed, was too large in the cup, to the point I was able to inch the material together above the breast, about an inch on each side. Also the band was too tight, even putting an extension on I wouldn't be able to wear is comfortably.
I returned it with no issues and am still contemplating ordering a 50C, to see if that would fit any better.
