True Alex. However, that is the point I was making. Many descriptions of a female charactor by authors tends to describe their vital statistics, age and job. It is less common to sescribe sombody as slight, lanky etc.
You are probably right about the bra size, but the UK still usues inches for it's clothes sizes. I would have difficulty visualizing metric in writing about a constricting corset, since it would mean little to me or my local readership. But a fair point and I will bear it in mind in future.
