This dress, named the "Trapez," is one of the breakthrough works of the young Yves Saint-Laurent, who then worked for Christian Dior. The loose waist and the simple silhouette are remarkable features and probably the starting point toward the next stage known as the A-line. Highly sophisticated techniques of Haute Couture such as precisely calculated darts and ironing, realized this clear form.
This dress is one of the first collections introduced by the young Saint-Laurent, who took over Dior's fashion house after his sudden death. The minimalism in this work, eliminating any decorative factors including flashy colors, patterns and materials, is very interesting as a step towards the simple mini dress in the coming 1960s.
