Which Saint Laurent handbag, introduced in 2013, has a trapezoidal shape and the brand’s initials on its front?

The Saint Laurent Sac de Jour is the handbag introduced in 2013 with a structured trapezoidal shape and Saint Laurent initials on its front.

The name is French for “day bag,” reflecting the design’s intended role as a spacious, polished everyday handbag. It has top handles, expandable sides and a detachable shoulder strap, allowing it to be carried in more than one way. The silhouette is often compared with classic work or doctor’s bags because of its firm construction.

The Sac de Jour arrived during the creative direction of Hedi Slimane, who helped define a sharper, more modern Saint Laurent image. Its front hardware usually displays the initials YSL, a logo strongly associated with the fashion house.

It should not be confused with the Saint Laurent Kate, LouLou or Sunset bags, which are generally smaller shoulder or evening styles. The Sac de Jour is most recognizable for its roomy structured body, accordion-like side expansion and restrained branding.
