Ask yourself this one question: do you own side-striped denim [1]? If not, girl, you need to get your hands on a pair of these true blues, because the race car effect [2] is pulling ahead, full throttle. During the latest Fashion Month, we saw the trend all over the streets [3], from New York to Paris. Ladies were either rocking the Calvin Klein Canadian tuxedo [4] in varying shades of denim or allowing a darker panel to attract eyes downward, drawing attention to a pair of fabulous shoes or an ultradistressed hem. Ahead, get inspired by a few of our favourite side-striped denim moments, then scoop up some of these of-the-moment jeans to work into your rotation.
