Cotton linen blend. Beautiful detailing. Lightweight knit. Very soft. In excellent used condition. This is a very versatile piece. It works as a stand alone top or shell underneath a blazer. Also looks great over a (crisp white) button down shirt. Size marked large but it’s quite fitted. Would fit size 10-12 more comfortably. Always hand washed in sweater shampoo and shaped flat to dry. Smoke and pet free home.
