To complement the sail-worthy garments and sporty silhouettes shown on the runway, Bureau Betak erected a yacht-theme backdrop for the September 6 Lacoste show inside the Mercedes-Benz Fashion Week tents at Lincoln Center. Guests sat on concrete-like surfaces that also covered the runway, while the half dozen or so sails erected as the backdrop were firmly anchored to the floorboard.   Photo: Jamie McGregor Smith
