Partial sounds like it could be a good choice as your quite petite … I would have said partial or unders but not overs …. Just going on the reasons Dr have said to me
275cc or 300cc would look lovely
If it’s any help I had very little breast tissue to work with (34a but didn’t fill the cup) & got 350cc unders (below is day 10 post op) I’m about 10-12 kg heavier than you but my weight is mostly in my lower half
