Givenchy creative director Riccardo Tisci directs a visual meeting of minds in  Dazed's 20th-anniversary special October issue, with former Dazed  fashion director Katy England and art shaman Matthew Stone combining to  create a darkly decadent extravaganza. Many of the models discovered and  championed by Tisci present personally chosen pieces from his six-year  reign at Givenchy.
