Hermès · ultra luxury
By Arielle · Catalogued July 2026
Originally launched in 1935 as the 'Sac à Dépêches,' designed under Robert Dumas, with a trapezoidal silhouette, single reinforced handle, four brass feet, and a flap top secured by a double-belted turn-lock closure. The bag is older than the Birkin (which was introduced in 1984) by roughly five decades. It gained its current name after actress and Princess Grace Kelly was photographed carrying one to shield her pregnancy from paparazzi in the 1950s; Hermès officially renamed the style for her in 1977. Each Kelly is handmade by a single artisan and reportedly takes 18–25 hours and roughly 680 hand stitches to complete.

A 1930s bag for carrying saddles became the first It bag the day a princess used it to hide a pregnancy.
Origin
The Kelly began in the 1930s when Hermès shrank a bag built to hold saddles into a structured handbag for women, the Sac à dépêches, launched in 1935. Simple, solid and roomy, it was made to carry a lot in a refined shape.

Culture
Grace Kelly fell for the bag while filming To Catch a Thief in 1954. In 1956, newly the Princess of Monaco, she was photographed using it to shield her pregnant belly from the cameras. Sales jumped overnight and the bag became the first true luxury It bag.
Good to know
Everyone called it the Kelly long before Hermès did. The house only changed the name from Sac à dépêches to Kelly officially in 1977, more than twenty years after that famous photo.

Articles on the Kelly and Hermès from our verified experts.
Hermès uses no serial number, so the blind stamp, the craftsman's mark, and the hand saddle-stitch carry the read. The era cutoffs and hardware tells that matter on a Birkin or Kelly, and why no marker is proof.

On resale the two cost almost the same size-for-size, so the real choice is shape and how you carry it. What each lists for now, and the steep small-size premium on both.
