A standout piece of 1990s archival Italian tailoring from the Yves Saint Laurent Pour Homme line, this long-sleeve shirt is a pristine deadstock vintage item in brand-new, unworn condition. Made in Italy from high-density pure cotton, the fabric features a unique slubbed tweed-look texture with a multi-tonal grid check. The rich weave blends denim blue, dark navy, clean white, and subtle burgundy windowpane accents, giving it a tactile, sophisticated depth. Sartorial details include a sharp semi-spread collar, pearlized four-hole buttons, adjustable cuffs, and the iconic YSL monogram embroidered in contrast white thread on the chest pocket. Brand new, complete with original tags, factory clips, and presented in its original black YSL gift box.

Women's Sizing & Style Guide Fit & Sizing Guide: Men's Size M/L (Collar 16 / 41). For women, this masculine cut offers a fantastic oversized "boyfriend shirt" or lightweight overshirt fit. It fits comfortably on US 8–10 (UK 12–14 / EU 44–46) as a relaxed layer, or creates a chic, editorial statement on smaller frames US 4–6 (UK 8–10 / EU 40–42).

Alternatively, tuck it into a pencil skirt, roll the sleeves up to the forearms, and style with silver jewelry to accent the cool blue tones.
