This post is for the hardcore fashion lovers.

The De Young Museum in San Francisco is hosting the Yves Saint Laurent exhibition, its only stop in the U.S. You can find more than 120 of the designer’s haute couture pieces. The work presents over 40 years of work, from his time at Dior to the final Spring/Summer 2002 collection.

YSL has been known for revolutionary pieces such as the first tuxedo for women (dubbed “le smoking”) in 1966 and introducing multicultural kimonos, Indian tunics and African prints into the mainstream.

Here are photos from the the De Young Museum opening.
