Its most defining feature is the sleek Mandarin (band / grandad) collar, offering a sophisticated, modern-minimalist silhouette that bridges casual elegance and high fashion. Additional details include dark mother-of-pearl style buttons, rounded cuffs, and the iconic YSL monogram embroidered in tonal navy thread on the chest pocket. Complete with its original tags, hanging seal, 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, the collarless band design elevates this into a chic oversized tunic or "boyfriend shirt". It fits comfortably on US 8–10 (UK 12–14 / EU 44–46) as a relaxed layer, or creates a sleek, avant-garde silhouette on smaller frames US 4–6 (UK 8–10 / EU 40–42).
