Hey, I’m 5’7 and weigh the same as you, I was a 34a, I had 380 round implants over the muscle on the 21st of may, when I i first had them done they were so round, high and looked stuck on but I’m almost two weeks now and they are settling really well, everyone I have showed them to in person thinks they look very natural! I couldn’t help but try on one of my mums bras (she’s a 34d) and it fitted perfectly! The surgeon will suggest size and implant that best suits your body type and frame though xx
