I'm 5'7, 175 pds and like a loose fit. I ordered size Large which was perfect but had to shorten sleeves by 1inch. Overall quality is nice, inside lining very nice but the buttons feel a bit subpar. very light white metal, feels like plastic and no spare buttons. Two buttons came undone the first wear. Jacket falls well and is quite warm, more like a fall jacket than a suit jacket. Came from HongKong to Montreal Canada in 3 weeks. Overall happy with my purchase.
