I had an interesting experience at M&S yesterday.
I went for a bra fitting. I know they're not brilliant but Bravissimo etc are over an hours drive from me.
Anyway,when I arrived I was told that they have changed the way they fit bras. No measuring. She talked to me about clothes size,bra fit,what style I liked etc and then disappeared to the shop floor. When she came back the bras she had chosen were a perfect fit.
She had used her judgement on fit and possible styles. All good. I was impressed.
