Victoria Beckham and baby girl Harper donned matching tartan ensembles en route to NYC for Fashion Week. The posh mom styled a short-sleeve Miu Miu sweater with a Peter Pan collar over a tartan miniskirt. Opaque tights added to her schoolgirl style, while her suede Walter Steiger booties lent a touch of sophistication. We completed Victoria's edgy look with a rose-gold watch and a quilted shoulder bag. Mimic this trend by pairing your favorite plaid pieces, from blouses to pants, with a saturated solid to balance the look.
