Stripes, squares, diamonds... geometric shapes are still going to be everywhere this winter. Both the  haute couture and ready-to-wear spring/summer collections were alive with geometrics, and the trend is showing no signs of abating.

Blouses, skirts, trousers or coats inspired with hot colours and lines will no doubt help us get over our winter blues - and will make a change from this season's grey.

Geometric shapes mix really well, so wear a combination or just one piece. By wearing a variety of silk and matte materials, you'll build up a contemporary look fit to parade from New York to London in.
