Singer and star of Smash Katharine McPhee attended an event in NYC last night looking superslick in a pair of black leather pants. We too are huge fans of the leather look, but as of late we've been searching for a new way to rock our favorite pairs — that's where Katharine comes in. We love that instead of the typical sexy or edgy vibe, the actress opted for a preppy feel that's still totally night-out appropriate. Katharine started with a jewel-collar blouse by Equipment — shop the white version here ($310) — then topped it with a cozy gray crewneck sweater. On bottom, she matched her leather pants with sleek leather booties, then accessorized with a black clutch and just a few gold baubles. Mimic Katharine's latest with our editor-approved pieces below, and note: if you're looking to inject a little more glamour, all you need is a bold red lip to finish it off.
