Sienna Miller was seen strolling in stretch twill jeans by Kill City—and we can’t deny the fact that she’s killin’ it! Her outfit is simple, chic, and classic Brit. An ensemble we could see Kate Moss strolling in just as easily. Her light wash jeans are combined with a graphic t-shirt, black chunky heel boots, and a fuzzy jacket to protect her (stylishly) from the elements. This is the kind of classic rock’n'roll it-girl off-duty look we adore.
