Hi Marianne, unfortunately your cup size can not be determined exactly! I’m the same as you and still at the researching stage and have been so for a while but I’m still new to the forum. Your surgeon will recommend a few sizes to you to help you achieve the size you’re hoping for (providing you have enough breast tissue for this size implant, etc…). You will be able to try different sizes on at your consultation to get a rough idea however once your breasts and softened and dropped they may be slightly bigger or slightly smaller than the cup size you had in mind, which I personally think doesn’t matter, as long as you’re happy with the size on yourself, cup sizes are just letters and numbers, 🙂 xx
