New York Fashion Week welcomed a fresh batch of trends for spring 2011, from long skirts to wide-leg trousers, sheer fabrics to eye-popping prints. But who wants to wait six months to try them on? We’ve distilled 21 salient pieces from the New York runways — including Proenza Schouler’s neon floral frocks, Doo.Ri’s chain rings, and Rodarte’s gathered plaid skirts — and shopped the city for affordable approximations (you know, for those of us unwilling to drop a month’s rent on a dress). For unabashed trend-watchers and bargain-lovers, here’s how to dress like a Rachel Comey, Marc Jacobs, or Vena Cava “It” girl for $200 or less.
