I also purchased this item on Mercari. The tag says "L," but it feels like a Japanese size "M~L." There are some small black dots, but they are not very noticeable. Please refer to the enlarged images. Here are the measurements, taken by a layman, laid flat: Shoulder width: 55cm Length: 66cm Width: 61cm There are magic marker marks on the abdomen and cuffs. Please refer to the images. I have many other items for sale as well. Please take a look! ☺︎ GLOBALWORK RAGEBLUE BAY LOW SEEDLER beams ABERCROMBIE&FITCH HOLLISTER AmericanEagle adidas underarmour Newbalance nike puma oakley desente umbro Reabok Nike, Under Armour, New Balance, Adidas, Umbro, Myprotein, Puma, Descente, Le Coq Sportif, Oakley, Abercrombie & Fitch, Hollister, American Eagle, Rayzy Blue, Beams, Global Work, Champion, Purple & Yellow, Everlast, Fruit of the Loom
