Please guys. I have been googling all night and cant find anything about unpadded cups leaving marks on breasts

I apologize, Katana, as I'm just guessing...
Maybe the cup is too small? Meaning, the actual cup, not the letter size.
I forget which blog I was reading, but...  She's "well endowed" like you, and has learned a few things...  Among them, protrusion and cup size, where the breast is full (top or bottom), details like that.
Might've been Hourglassy.com, or "Sophisticated Pair".

Anyway - What about looking into alternate brands? Full-ly, I think was one, which has larger (deeper) cups. Don't know if they're around near you, Sears used to carry them - haven't checked recently. Available online.
I'll see if I can find some others....  I think the standards are Olga, Lillyette, Bali. And the standard stores, Torrid and Lane Bryant (Cacique.) 

I'll need to check from home, work doesn't give me enough flexibility. ;-)
