YSL Bags: Every Saint Laurent Bag Explained and Which to Buy

Saint Laurent bags are built around the gold Cassandre, the interlocking YSL monogram, and almost every model comes in several sizes. Here is how the house range works, from the quilted Loulou to the Sac de Jour, with the full bag edit and the Saint Laurent hub a click away.

The quilted bags: Loulou and its family

The Loulou is the bestselling Saint Laurent shoulder bag: quilted matelassé leather in a Y pattern, a sliding chain strap and the Cassandre on the flap. It is named after Loulou de la Falaise, one of Yves Saint Laurent’s muses, and comes in toy, small, medium and large. Our Loulou size guide compares them.

The Kate is the flat chain bag with the Cassandre in the centre, and the wallet on chain is its smaller cousin. See the wallet on chain and mini bags.

The structured bags: Sac de Jour

The Sac de Jour is the structured top handle tote with the padlock, launched under Hedi Slimane in 2012. It has no logo on the front, which is why it suits the office. Sizes run nano, baby, small and large; the Sac de Jour size guide has the measurements. More totes are in our YSL tote guide.

The soft bags: Le 5 a 7 and the hobos

Le 5 à 7 is the soft hobo named after the French hour between work and evening. It sits close under the arm on a short strap. The newer Simone and the slouchy shoulder bags follow the same soft line. See YSL shoulder and hobo bags.

Evening bags

For evening, Saint Laurent makes slim clutches in satin, velvet and patent leather, many with only a small Cassandre. Our YSL clutch guide covers them.

Which YSL bag to buy first

For one bag that works every day, a small Loulou in black with gold hardware is the safest choice. For the office, the Sac de Jour. For a softer, more current shape, Le 5 à 7. Prices are in how much a YSL bag costs.

Saint Laurent bag sizes at a glance

Most Saint Laurent models come in a range of sizes. Toy and nano hold a phone, cards and keys. Small and baby take a wallet, sunglasses and a small pouch. Medium and large carry a day’s worth, and the large totes take a laptop. Every Coveti product page gives the exact dimensions and strap drop.

Leathers and finishes

Quilted lambskin is the softest and the most delicate. Grained calfskin resists scratches and is the best everyday choice. Smooth calfskin shows the shape of a structured bag, crocodile-embossed leather adds texture, and suede is the warmest look for autumn. Hardware comes in gold, silver, bronze and black.

How to choose

Start with how you carry. On the shoulder all day: a Loulou with a long chain. Under the arm: Le 5 à 7. In the hand: the Sac de Jour. Across the body: a camera bag, the wallet on chain and the Kate on its long strap. Then pick the size for what you carry, and the leather for how hard you use it.

Black with gold hardware is the classic and holds its value best. Brown, deep red and taupe are the house colours this season.

Caring for a Saint Laurent bag

Wipe leather with a soft dry cloth, keep it out of rain and direct heat, and store it stuffed and upright in its dust bag. Keep chains away from perfume and lotion. Suede needs a soft brush and a protector spray before the first wear.
