Teal green ribbed knit layering top. Materials tag is missing but it is a cotton/polyester blend (info from the Anthropologie website). Size labeled M but fits more like a small, which is unusual for Pilcro. Pit to pit width is 18" and length from shoulder to bottom is 24". Excellent used condition, no stains or flaws, from smoke-free home. Thanks for shopping my closet! Discount on bundles of 2 or more items!
