I’m currently an A & am either havin 340 unders which will roughly b a D or 380 unders which will b about DD. Each implant is different on each person tho, ur surgeon will give u an idea on what size it will take u 2 xxx
Specific implant size doesn’t determine a cup size and your surgeon will suggest a size by comparing to what you request and what he or she measures and wether it will fit your frame and wether you have enough tissue
Going under the muscle has a 20% more less likely of rippling as more coverage I’d say not so much about 20cc is lost from the original implant size so not so much differecce from someone who has had over the muscles
