I think 380cc high profile is just right for you.
You might have read my message in another post. My my stats are similar to yours.
I’m 4”9, 45Kg (7 stone), size4-6. Was a 32A.
Had 375CC High profile round in 2017. Now 32D. But defiantly looks like a full C cup.
I’m going to have my second op in end of August and want to go bigger. It’s been 3 years post op now & honestly they don’t look big at all. Even on my small frame.
