Vintage Yves Saint Laurent Leather Belt Geometric Buckle Late 1970s Dark Brown

A rectangular buckle in silver-tone metal anchors this Yves Saint Laurent belt, set with a gold-tone plaque bearing a geometric black and gold 'Y' motif to the front and an engraved YSL Cassandre logo in a tightly kerned serif on the reverse. The dark brown leather strap runs slim and straight, broken only by the natural contouring at the edges and the visible scuffing from years of use, with the buckle showing both tarnish and wear to the finish. No interior label is present; the design is identified by its hardware and overall construction.

Crafted in France, the belt offers a substantial hand with a smooth, matte finish, its width set at 2.8 cm—a proportion that sits between formal and everyday. The buckle can be worn facing either the graphic 'Y' or the Cassandre signature, each side marked by visible surface scratches and minor material loss consistent with long-term wear.

This piece dates to the late 1970s to early 1980s, an era when Yves Saint Laurent was defining Parisian style from 5 Avenue Marceau and dressing Catherine Deneuve for the screen and the street. The buckle’s geometric motif and early Cassandre logo are both signatures of the founder’s hand—graphic, assured, and unmistakably of the house’s golden age.
