Purchased at a sample sale, I believe this is a version of the marlow shirt but with no buttons. Cute over shorts with a tank or bikini top! No label tag or size tag but could work for s - l depending on how oversized you want it to be. I’m a medium and it works great so listing as such. Some of the stitching work on the inside looks slightly unfinished around the collar but doesn’t effect integrity of the top.
