Many of the radical changes in fashion developed in the streets of London, with such gifted designers as Mary Quant (known for launching the mini skirt) and Barbara Hulanicki (the founder of the legendary boutique Biba). Paris also had its share of new and revolutionary designers, including Pierre Cardin (known for his visionary and skillfully cut designs), André Courrèges (known for his futuristic outfits and for launching the mini skirt along with Mary Quant), Yves Saint Laurent (known for his revolutionary yet elegant fashions), and Emanuel Ungaro (known for his imaginative use of color and bold baroque contrasts). In the United States, Rudi Gernreich (known for his avant-garde and futuristic designs) and James Galanos (known for his luxurious ready-to-wear) were also reaching a young audience. The main outlets for these new young fashion designers were small boutiques, selling outfits that were not exactly 'one-offs', but were made in small quantities in a limited range of sizes and colors. However, not all designers took well to the new style and mood. In 1965, Coco Chanel mounted a rearguard action against the exposure of the knee and Balenciaga resolutely continued to produce feminine and conservative designs.
