I would suggest choosing the biggest I was in decided between 380 and 410 after specking with sergeon he said to go for the biggest because that way I wouldn’t go bk wishing I was bigger. I went for the 410 I was a b cup and now a dd. my op was in April and I’m not sure if now I’ve got use to the size I now wish I was bigger, but aparently a lot of people do because of boob greed. I would speak with dr on the day and see what he says but my answer would be get the biggest xx
