Horst is best known for his photographs of women and fashion, but is also recognized for his photographs of interior architecture, still lifes, especially ones including plants, and environmental portraits. One of the great iconic photos of the Twentieth-Century is "The Mainbocher Corset" with its erotically charged mystery, captured by Horst in "Vogue"’s Paris studio in 1939. Designers like Donna Karan continue to use the timeless beauty of "The Mainbocher Corset" as an inspiration for their outerwear collections today. His work frequently reflects his interest in surrealism and his regard of the ancient Greek ideal of physical beauty.
