Received the wrong item but kept it. Edit: Ordered a few years later in 2021 was slightly larger so I tried XL for a roomy fit, it turned out to be the same size as average. Then I ordered XXL and it was the size I wanted. While this wasn't always the case, it turned out to be 2 sizes too small. The material is a bit thick and stretchy, which I don't think cotton should have, but it's not far from a classic 100% cotton shirt.
