My op is on 13 dec, as im so narrow im wonderin if 300/340 standard cui will fit on me?! I really dont want to go any smaller as I am aimin to b a DD after. Does anyone no if these implants come in different projections, as from wot I understand if u have a higher projection, the base is narrower?? And wud I have to pay more for high profile implants? Thanx xxx
