I just bought a Kiton Jeans, how can I know thats authentic? Athere are a few things about the jeans that an inattentive or low-budget counterfeiter might not do - - first, they should almost always (always?) be button-fly, and the buttons are these substantial things on a ball pivot that look like they would be expensive to make/counterfeit. second, the rivets all have the Kiton logo on it third, the jeans should all be selvedge btw, they also have these very light "jeans" that are cut like jeans but aren't made of denim - they are made of cotton that looks like polyester and are always in horrible bright tacky colors. believe it or not, those are authentic as well. but still terrible.
