Learn the rules, then break them. That’s exactly what former shop owner Mik Serfontaine did when he couldn’t find the perfect-fitting pair of jeans for his L.A. boutique. He studied design before launching his eponymous line of second-skin jeans, so not only are they designed with the edgiest of details like zip-off waistbands and strategically placed shredding, but Serfontaine jeans use bi-stretch fabrics that meet exacting standards of fit. Christened “the most rock-and-roll jeans around” by Allure magazine, Serfontaine has attracted a cult following that includes Sienna Miller, Kate Hudson and Jennifer Aniston.
