Marc by Marc Jacobs Merino Wool Rib Knit Size: S (Fits like a Japanese size 9, or a US size M) Color: Off-white This knit has a classic silhouette and is easy to match with anything. I wore it often, so there are some stains under the arms. They are not very noticeable, but please refrain from purchasing if you are sensitive to such things. See images 6 and 7.
