Soft lambskin, a sculptural vanity silhouette and quilted volume: the YSL Gaby Vanity calls for care that is considered, light and specific to the material.

The vanity case shape has roots in vintage travel cases, and Saint Laurent's Gaby reworks that history into a quilted, structured-yet-soft bag built in lambskin, one of the house's signature materials. Lambskin's appeal is its softness, but that same quality means it shows handling more readily than a firmer hide, so the case for a deliberate, gentle ritual isn't just aesthetic, it's what keeps the quilting and the leather looking considered rather than worn thin.

Start with the Gaby Vanity in lambskin

This guide focuses on the lambskin version of the Saint Laurent Gaby Vanity. Always check the care information for your exact bag and finish before treating it. Lambskin is best approached gently: avoid aggressive rubbing, excess moisture and heavy applications of product.

Clean the quilted channels with a light hand

Begin with a clean, dry, soft cloth to lift loose dust. If the bag’s care guidance allows a liquid cleaner, place a small amount of Gentle Leather Cleaner on a clean microfibre cloth, never directly onto the bag. Use the cloth’s edge to work carefully along the quilted channels, without forcing liquid into the seams or saturating the lambskin. Keep pressure light, let each area dry fully, and do not scrub at a mark that does not lift easily.

Our Gentle Leather Cleaner is suitable for leather, suede, canvas, fabric and nubuck. On leather, use small, gentle circular motions. Always follow the bag maker’s care guidance and patch-test on an inconspicuous area first. If the surface changes, stop and seek specialist advice.

Protect the leather, not the chain

A suitable protector may help shield the bag material from everyday exposure when used exactly as directed. The Preventive Protocol Kit includes a breathable protector for the materials listed in its directions. Confirm that the exact finish is suitable, patch-test first and keep product away from the chain and other hardware.

A leather protector is not a metal treatment. We cannot promise that it will prevent chain tarnish or stop hardware from marking leather. Keep metal details dry, avoid applying leather products to them, and follow the maker’s guidance for hardware care.

Keep the silhouette at ease

After use, empty the vanity and let it air in a cool, dry place. When storing it, support its shape gently with clean, colourfast soft material if needed. Avoid overfilling it, crushing the quilted panels or placing weight on top. The aim is to preserve the bag’s natural form, not make it look untouched.

A small ritual for a standout piece

The Gaby Vanity does not need an elaborate routine. Identify the material, clean with restraint, allow it to dry fully and use only treatments confirmed as suitable. That measured approach lets the lambskin remain part of your rotation while respecting its soft finish and sculpted shape.

Preserve the past. Protect the future. Once you have confirmed your bag’s care requirements, explore the Archive care rituals.
