U.S.A. customer here, I always go for small size but then I read comments from here that you size up for proper fitting. ordered medium but still runs small for my build. Other than that, jacket is good, outer shell material although faux leather is ok, lining is good too but don't expect it to warm you during winter.
though the product is very accurate with size and quality but shipping is so slow and was delivered very late. it took 3 months to deliver and even paying the shipment charges it was not delivered to home address I have to pick it up from station and have to pay some charger as well . So don't recomend
