Dual-identity denims are a thing and here's why. The jeans of the moment look vintage – straight leg (zero cling, zero taper, zero kick flare), cut off at the ankle and in classic Levi's 501 blue – but they're brand new and prime for those days when you don't want to look like you tried too hard, but just so happen to be rocking the coolest denim going. Riley Keough (centre) chose to wear them on her über-unconventional and very cool hen party (attended by K-Stew, FYI) prior to her wedding to stuntman Ben Smith-Petersen. Meanwhile, Victoria's Secret babe Alessandra Ambrosio (left) nails queen-of-the-LA-errand-run cool in her vintage-patched, turn-up jeans. Lurve.
