I belief ethers go buy Japanese sizing charts so figure about 2 sizes lower. I wear an American Large T-Shirt and these were a little tight (which I suppose is the point haha!) but I think if you are an American medium-large you’d probably find that these work for you. 5 shirts total: Three XL’s and Two XXL’s $12 total
