On the neck—an ample Fichu, very prominent, the point of which behind goes under the jacket and the ends before go under the stomacher

The fichu proper, introduced by Marie Antoinette, not before the décolletée style of toilette made it positively necessary, was nothing more than a lace kerchief worn crossed over the shoulders.

She wore a dress of filmy white stuff, embroidered with bunches of pale mauve thistles, a full fichu, and a large mauve hat with wide mauve ribbons, tied in front in a large knot where the fichu was crossed on her bosom.

Assistant Van admired her elegant slenderness, the gray tailor-made suit, the smoky fichu and as it wafted away, her long white neck.
