Ponytail wigs came in a wide range of styles: a bunch of loose curls caught up in a band; a tasteful braid; or a smart pigtail ending in one curl (for majors), two (for brigadiers), or a knot called a catogan, formed by tucking the end of the tail into the band.

For extra dash, the ponytail might be covered with a bag or dressed up with a large bow that might be accessorized with a matching small bowtie, called a solitaire, fastened to the wig in back.

Soon even these wigs grew tiresome, but no self-respecting man would ever bare his head. So, for a quiet evening at home, he covered his locks with a lavishly embroidered cap edged with fur.
