At YSL, designer Stefano Pilati used quotations from Plato to explain why he combined female detailing with a masculine silhouette.

"The original human nature was not like the present ... the sexes were not two as they are now."

Pilati underscored the union of genders with a line for men made in fabrics normally worn by women -- crepe de chine, organza, shantung and silk voile, all fabrics which float rather than fall.
