Given that it was Valentine's Day, it was only natural that there would be romance in the air at the Marc Jacobs show Monday night. But Jacobs skipped the romance, and went directly to sex. As couples rushed to make dinner reservations, the fashionable crowd attending Jacobs' show -- including Martha Stewart, Josh Duhamel and his wife, Fergie, Leighton Meester, and Sofia Coppola -- rushed against traffic and a clogged sidewalk full of stargazing gawkers, to make it to Jacobs's show, which starts notoriously on time. But once inside, what a show it was. Jacobs presented a retro futuristic trip back to the 1940s, recasting the silhouette of the Andrews Sisters in freshly sexed up tight pencil skirts, rubber and cellophane blouses, and stretched felt. While many designers are still following the lead that Jacobs started a few seasons ago by reinventing the 1970s, Jacobs was having fun deconstructing yet another decade. Nearly every model sported a petite beret held in place with a near-invisble cashmere chin strap. The innocence if these tiny berets made the clothes feel even more risque as models strutted by enormous white vinyl pillars. The result was Jacobs tampering with the memory of an innocent era, and turning it something far less chaste, but far more fun.
