The most inventive Fashion Week concept goes to Rachel Antonoff, who held her Saturday show at Fiorello H. Laguardia High School Gymnasium where the band The Like performed in a prom-like atmosphere complete with punch bowls. Invites for Antonoff’s “The Dance” included ripped pieces of lined notebook paper and hand-written notes asking “Will You go to the dance with me?” and a “Yes” and a “No” box for invitees to check with a small number two pencil attached by a string.
