Leave it to Victoria Beckham to look so prim and posh while doing some nighttime shopping in London. The designer wore a printed Prada skirt and tweeted her obsession with the geometric print. Up top she covered up in a black sweater, on bottom a pair of pointy black pumps, then carried this Victoria Beckham two-tone bag ($3,000) and shielded her eyes with her signature oversize sunglasses. If you don't yet have a geometric-print skirt in your closet, allow Victoria to inspire you to get one pronto. Shop our favorites, including this very similar Tara Jarmon geometric skirt ($240), below.
