I usually wear American XL, so using ordered shirts according to their size chart for 2XL. Received them and they were more like Youth Medium. Tried to resolve with merchant but they refused to refund unless I fully paid for shipping back to China (which BTW would have cost more than the order!). Tried to resolve through PayPal and they wanted me to contact the FBI (really?!!) to start a legal investigation. They're clueless to actual American sizes. SAVE YOUR MONEY!!
