hey hun, the best thing to do is write all your questions down as I went blank in my first few consultations and came away without asking everything I wanted to.
Unders are placed under the muscle and usually for girls with little breast tissue. Overs are over the muscle and mostly used for girls who already have a fair amount of breast tissue. Then there is the projection. You can get all different types of projection which is how much they stick out and your surgeon will advise you which projection will most suit you.
With implants there are the CUI’s which are the standard implants you will be offered and I think most girls end up having these. If you prefer, you can upgrade to the Naturelle range where you’d have a choice including Responsives or Soft Touch (again your surgeon will advise what is best for you) xx
