Kate Bag

Saint Laurent introduced the Kate Bag in the early 2010s, naming it after Kate Moss during a period when the house frequently named its shoulder-bag lines after models and muses rather than places or archetypes. Its defining details, a centered YSL monogram plaque and an optional antiqued chain-link tassel hanging just below it, gave the silhouette a distinct, instantly identifiable look separate from Saint Laurent's other quilted or chevron-stitched bags of the same era.

Over more than a decade in continuous production, the Kate has been offered in a wide range of leathers including smooth calfskin, suede, and croc-embossed finishes, and across a shifting size range. Saint Laurent has since discontinued the original small size from its catalog, though it remains findable on the pre-owned market; the current lineup centers on Small and Medium, each offered with or without the chain-link tassel.

The Kate is repeatedly described by resale platforms and style guides as one of the most popular Saint Laurent styles, a status built less on a single viral moment and more on remaining one of the brand's most consistently restocked and resold shoulder bags for well over a decade. That steady, unglamorous consistency is itself part of its appeal, it's a known quantity for buyers who want a reliable Saint Laurent shoulder bag rather than a seasonal trend piece.

The optional chain-link tassel has become something of a signature detail in its own right, giving the Kate Tassel variant a slightly more decorative, evening-appropriate look compared to the plainer non-tassel Kate, and buyers frequently choose between the two based on how dressy they want the bag to read.
