Simple and stylish collarless jacket, currently trending with a double-face design, allowing for reversible wear. I understand that at the time, Jil Sander had few stores, and this item was only available as a single piece in one size upon domestic arrival. This item features a balloon sleeve design. It is a valuable piece, as it was rarely imported domestically, and I have never seen another one like it. This is an authentic item purchased at the Jil Sander Aoyama store (now Omotesando store). - Color: Black - Design: Collarless, zipper closure, double-face, reversible - Material: Polyester, polyurethane, nylon Please refer to the images for material confirmation. Thank you for viewing.
