The legendary tome published alongside Raf Simons and Francesco Bonami’s 2003 exhibition at Stazione Leopolda, Florence. Co-curated by Simons and Bonami, The Fourth Sex explored the emotional and visual extremes of youth, reflecting on the complex and contradictory state of adolescence and the power of fashion as a tool for self-expression and disruption. Over more than 400 pages, the catalogue is constructed with images of fashion, art, music, cinema and the news, accompanied by an anthology of writings that mixes poetry, literature, journalism and research highlighting the increasing importance of the teenage tribe in contemporary society. Including works from Mike Kelley, Ed Templeton, Juergen Teller, Britney Spears, Brett Easton Ellis, Jean Cocteau, Helmut Lang, Tracey Emin and Larry Clark amongst many more, The Fourth Sex is an essential youth culture document.
