Most people have a slight difference, but once the implants are in there they usually look the same size. Remember the surgeon does know best and he is trying to get the best result for you Also bear in mind that using different sized implants doesn’t work a lot of the time; I’ve only seen a couple of people who have had different sized implants as well as a nipple lift that have looked more or less symmetrical after about 3 months or so, If you’re still unhappy then get a second opinion xx
