WILLIAMSBURG Suffering from Fashion Week withdrawal? Keep the party going with the Williamsburg Fashion Weekend, holding its Fall/Winter 2011 show at Glasslands this weekend. The Brooklyn fashion staple features a number of forward-thinking local designers presenting their clothes alongside live music and DJs. On Friday, expect strong showings from Lana Weiss’ technicolor We Do This All The Time line, upcyclers Ruffeo Hearts Lil Snotty, and SDN’s 20s-influenced ecofriendly wear, as well as music from new wave popsters Sensual Harassment and the lounge-loving Matt Mikas. Punks Total Crap Uninc. and sexy swimwear maker Alexander Campaz are among Saturday’s designers.
