The 70's are back, my friends, and the Marc Jacobs Spring 2011 show was a strong testament to that fact. We saw beautiful, colorful, flowing midi and maxi length skirts, peasant blouses and wrap dresses come down the runway. Marc Jacobs a bit pricey for you? There are plenty of 70's inspired pieces available for spring in every price range - Nordstrom, Piperlime  and Topshop have some nice things.
