Single stitch. Guessing 100% cotton or a blend of. Guessing size L/XL. But, don’t go by a guess in size. See all 12 pics for details and enlarge each pic for a closer look. Any wear, soiling/spots/stains (see pics 8 and 9) undone area on seam area of left sleeve (see pic 10) or anything else is to be considered character.
