If Sli­mane can lay claim to defin­ing much of the wardrobe of 21st-cen­tu­ry men, Yves Saint Lau­rent undoubt­ed­ly did so for their female pre­de­ces­sors. He is the most impor­tant fash­ion design­er of the past 50 years. “I tell myself that I cre­at­ed the wardrobe of the con­tem­po­rary woman, that I par­tic­i­pat­ed in the trans­for­ma­tion of my times,” Saint Lau­rent said, upon his retire­ment. Those sound grandiose state­ments, but they’re true.
