Aristocratic flair, unerring taste, and the looks of a Visconti hero made Jacques de Bascher a muse to Karl Lagerfeld and the tempestuous lover of Yves Saint Laurent. This book, based on interviews with those who knew, admired, or loathed him, is a deep dive into the '70s and '80s, those crazy decades that consumed Paris, its cliques and fads, of which he was one of the most singular figures.
