Hi Kirsty, We are friends already. I had 385. im very happy with the size. I was 36a before. My advice – go for 415. there won’t be that much difference. At first you will probably think that they are big, but once you get used to them and the swelling goes down, they would seem a bit smaller. im only 3 wks po so very early days, but I went to M&S today and picked up 36D and 36DD. DD was big but D was ok and to be honest I got a bit upset that DD was big. =))))) I also work out a lot and had partials. it will be ok, but I won’t do any chest exercises anymore just to be safe.
