The catalogue to Pallant House Gallery’s latest exhibition features a favourite anecdote. It is 1924 and a competition is being held to find the woman with the most pleasing vital statistics. As a paradigm, the judges choose the Venus de Milo. Thousands of women queue up to find out whether their measurements — not only bust, waist and hips, but thighs, calves, neck, wrists even —approximate closely enough to those of the ancient sculpture to earn them the prize of £5.
