If you are already 36B, or 34D, the medium and large will be too small width wise. I would go for the contoured large cups. They are marvelous, btw. Lighter and the rims does not hurt except when you apply too much pressure. I was a small 34A/32B when I started noogling with medium cups, but didn't use the medium too long as I outgrew the medium since my breasts were growing sideways, and the medium cups didn't hold them in. I switch to large cups, but for some reason, I could not get a suction long enough to hold them.

The contoured large is perfect for those that have already the breast mass/weight, since you need the fat on the sides for the contoured to keep suction/pressure.
