Marks & Spencer Speckled Sweater Vest

Is a size small but I’d say this is a medium, it’s from the UK where sizing is a bit different. I’m usually a medium and it fits me perfectly. Can be worn layered or on its own, I wore it as a top by itself In very good used condition! Some pilling, but the original fabric was like that too / goes with the style Wash in washing machine on cold and hang to dry Pet free and smoke free home
