I went for a fitting the other day and was told I was wearing completely the wrong size. Had been wearing 38B and was told I needed 34D. I tried on the one they recommended and the fitter said it fitted really well. I told her I thought it was a bit tight but she said it would loosen a little with time and was right for me. I wore it today and was uncomfortable all day. When I took it off I had welts across my back and into my breast from the underwire. Should bras be that tight? I must admit I did have a good cleavage in it but it was incredibly uncomfortable. Is that normal? Is it necessary to be in pain to be perky?
