Jesse corset sizing

I'm thinking of ordering the Jesse corset soon, but am unsure about the sizing. It says that a large is a C-cup (I'm a D-cup,) that it will fit a bust size of 36-38" (I have a 38" bust), & a waist of 27-29" (I have a 28" waist). While I think the measurements would fit pretty well to my body's size, I'm afraid that the cups won't fit. Has anyone else who is a D-cup ordered this corset in a large? Did it still fit pretty well in the cup area despite the fact that it's meant for a C-cup instead of a D-cup?
