Very pregnant, went to try and get some new bras today. The woman at M&S measured me under boobs and said I was 32 inches so would need a 38" bra, as you have to add 5 inches to the measurement.
AM Sure that is madness. Don't you measure under boobs and take that as back size and then across boobs and subtract to get the cup size?
Have been going to Bravissimo in recent years where they don't believe in traditional measuring but the last bra they measured me for (at start of pregnancy) was 30FF.
I couldn't face going into centre of town to get bras so thought M&S would suffice but ended up walking out after she recommended I try 38F.
