I am really bad at finding the right size when getting a bra, I have tried different methods and even I went once to get it measured at M&S ( I don't know if there are any other places around that till do it), but still after having it measured at M &S and buying it there on the spot I found out (on the next days) that the wires were digging in my skin. I don't seem to find a way to know (and be happy) with the size I buy.
Do you have any "fool proof " to measure yourself and know exactly your size? Do you go to get measured (where)? I would really appreciate some advice, I absolutely hate buying bras. It always feels like a "guessing" game.
