Penelope Tree’s beauty is commonly described as otherworldly, she herself referred to her looks as alien-like. The waif of a model embodied the youth-centric culture of the 60s and was often photographed by Richard Avedon, whose imagery of impossibly perfect women of the 50s transitioned to boyish gamines of the 60s, mimicking the shift in society’s ideal of beauty. Avedon’s 1968 portrait of Tree dressed in Pierre Cardin has come to represent the spirit of the 60s and was recreated in an editorial by Peter Lindbergh in the April, 2009 issue of Harper’s Bazaar starring Gisele Bündchen in a dress by Giorgio Armani and necklace by Roberto Cavalli.
