Hiya, It depends on what size you already are as they will be a different size on everyone. I’ve been trying to get an idea of what size implant gives you a C cup and it’s literslt impossible to know what size you’ll be until you’ve had it done and been measured. You can try the rice test but I don’t think it’s very accurate or I’ve heard you can try the implants in a sports bra to get an idea. Hope this helps xxx
