Estimated size M/L Heavy Long Blue Sleeve

This shirt has absolutely no tags in it 😂😫 I am normally a size S, height 5’2” and this was quite loose/long on me, so I would safely say a Size M and potentially fitting a size L. It is heavier than a standard long sleeve but not as heavy as sweater material. I would wear this as an oversized top with leggings and a scarf. Pockets on the sides of the shirt. In very good condition, only worn 1-2 times.
