I did that with bras too haha, I’ve never once been measured. I had 340cc overs, which is over the muscle, I’m not sure about partials you may have to ask your surgeon. I’m a size 10, 5ft 4 and was roughly a 36a, 340 was the largest I could go and my surgeon, mr traynor, said that they will look natural at a full c/ d, I’m only 2 days post op at the moment so can’t quite tell yet but I have a pic up if you’d like to add xx
