The cup size is too large. I have been measured professionally ALOT and I am always between a 44D-DD. Because I had read reviews of the cup size running big, I ordered a D. Still very loose. Also, not very supportive given my size. I was really just hanging loose and free. Boning and material are fine. Just really offers no support for bigger chest sizes. Also, because of the size and positioning of the cups, it "shelfs" and separates your cleavage and it's not very attractive. A great product for smaller sizes, but not for me. Returning.
