No other store follows the catwalks so closely or initiates its own national trends like Topshop, a mecca for high-street fashion. What looks like a teen hangout (similar to H&M) is really an insider’s source for designer knockoffs. Recently it pioneered high-waisted, wide-legged trousers and encouraged 70’s-style floaty tunic tops and bold prints. (Kate Moss launched her own line here.) Vogue and Harper’s Bazaar often feature the influential togs, and Hollywood luminaries including Gwyneth Paltrow and Sarah Jessica Parker flock to this flagship store for the latest trends: casual tees, ballet flats, beads, brooches, bags, and bangles at throwaway prices. Branches nationwide.
