"You wear your jumpsuit," complained the woman to her husband in a recent New Yorker cartoon, "but you never jump." Not many people do much jumping in their jumpsuits, either in this current return of the fashion or in previous ones.

The jumpsuit's big appeal is its ease: top and bottom all intact, no choice to make but what shoes to wear with it. No shirts to poke out of waistbands, no double layers of clothing to add to discomfort in warm weather.

The jumpsuit has recurrent revivals, usually as a reaction when clothes be complicated. The new versions, seen a lot this spring in Paris and Saint Tropez and worn frequently with Indian beaded moccasins, often borrow the details of men's military gear. Even though jumpsuits were a favorite relaxation garb of Winston Churchill, they really never have caught on in the same way for men here.
