Hi, I had exactly the same pre-op stats as you, 5foot6, size 8/10, 32a.. I had 420cc overs and I’m now a 32E but prob look around a D.. they look very full in a bra! I wish I had been allowed bigger, 420 is fine but they feel a bit small now I’m used to them. They look about normal for my frame, not like I’ve had them done at all so I think 440 would look perfect, especially if you want people to notice you have boobs 🙂 Feel free to add me to take a look at my 420cc pics if that’s any help 🙂 xx
