Hi Maria! My stats are similar to yours I’m just a little bit taller and I have just had 350cc HP unders which my surgeon predicted would take me to a D/DD and back to what I was before BF. I was also offered 400cc but went with the 350cc even though it’s the tiniest difference – 50cc isn’t even one cup size. Obviously it all depends on your measurements, tissue, skin etc but let’s say you were exactly the same as me then 400cc is definitelty going to give you a DD. Hope this helps honey xxx
