Loulou

Name: Saint Laurent Loulou Medium
Brand: Saint Laurent

Catalogued July 2026

The Saint Laurent Loulou is a soft quilted shoulder bag introduced by Anthony Vaccarello in 2017, as part of his spring/summer 2018 collection, and named after Yves Saint Laurent's muse Loulou de la Falaise. It is defined by the oversized Y-quilting on supple leather and the large metal YSL Cassandre monogram on the front flap, hung from a chain-and-leather strap. The puckered chevron stitching gives it a plush, pillowy look. It became one of the house's most recognizable modern bags.
