Jil Sander's overshirt blends 60% polyester and 40% silk in a textured tiger-stripe camouflage print across beige and charcoal tones. The technical silk chiné creates surface dimension, while a full-length zip closure and extended collar define the utilitarian silhouette. Dropped shoulders and finished cuffs on the long sleeves enhance the relaxed proportions, with patch pockets for practical styling. Layer it unbuttoned over a tee for contemporary urban ease.
