Hi MN ladies! I've lurked for a while on this forum, but this is my first post, so go gently on me. I'm pretty good when it comes to selecting clothes, but bras are a different matter. I'm at the point where I haven't really a clue about what size I am. i was about to take myself off to M & S for a fitting, but I've read that they're not very good. So, I got a tape measure and my under boob measurement is 28" and my round the boob measurement is 36". Should I be trying on a 28", 30" or 32" band? I don't really fancy taking an armful of bras into a changing room. Any thoughts?
