It's all about the limited edition, online-only and 'capsule' collections on the high street at the moment. From celeb-designed ranges to special ranges of 'key' pieces, they're all intent on building a buzz around a hard-to-find range. Warehouse are the latest to get in on the act, with their 'Modular' collection, which is available online and in two London stores (Argyll and Duke street). With a hint of the Louis Vuitton to the layered dresses and an 80s vibe to the whole lot, this is one to look out for if you're bored of tiered skirts and tea dresses. Dresses start from £45, skirts from £35, tops from £22.
