I'm 30 with 4 kids who I breastfed and they literally depleted me, I have nothing left. Looking to finally look like a woman but I don't want to go overboard, at the same time I don't want to regret not going a little bigger. I tried the Natrelle Inspira SRF520 and the SRM405 but couldn't tell much of a difference ... both habe the same base width, just different projections. I don't want stiff looking bowls but also don't want rockets. The 520 number just seems huge to me and the doc mentioned it's a D?! I went in wanting a "FULL B" although a C wouldn't hurt my feelings - I just dint want to seem unnatural or not proportional. I'm 5'1 and 105lbs if that helps?!
