At last night's 19th annual City Harvest event in NYC, Elizabeth Olsen and Chrissy Teigen gave us two fashion-forward plays on classic black and white. Chrissy played up her supermodel status with a tuxedo-style white minidress (that showcased her mile-long stems) and finished the look with nude strappy heels and a shimmering gold clutch in hand. Meanwhile, Elizabeth furthered her fashion-darling status in an anything-but-basic Chloé LBD with a statement-making ruffled neckline, which she tempered with understated black pumps. She didn't opt for jewels — but an ornate gold clutch proved just enough to dress up the look. Now that you've got the breakdown on Chrissy and Elizabeth's respective black and white styles, it's time to declare a winner: which evening-chic ensemble gets your vote?
