About as far-removed from traditional fashion houses as possible, Dutch duo Viktor Horsting and Rolf Snoeren have a surreal sense of design. Their collections are quirky (think 3-D motifs, from violins to mushroom clouds); their muses unusual (Tilda Swinton is their red-carpet ambassador); and as for their catwalk shows, their models have paraded down runways in silver-plated dresses with antlers sprouting from their heads, attached to their own lighting rigs and accompanied by live performances from Tori Amos and Rufus Wainwright. All this should make for a colourful retrospective, featuring weird and wonderful items from past collections and a specially commissioned installation.
