Peacoats

Rihanna may have been on hand to switch on the Westfield Stratford City Christmas lights and spread holiday cheer in London, but it was her blue striped pantsuit that had us cheering. The trendsetter layered a blue and gray striped top and matching trousers from Acne's men's Spring 2013 collection over a crisp white button-down, then slid on a men's cobalt Raf Simons coat and gray suede pumps for extra texture. As if her borrowed-from-the-boys style wasn't chic enough, the brunette beauty completed her eye-catching look with brilliant blue cat-eye shades, a bevy of gold rings, and a bright red lip. Get inspired by Rihanna's fashion-forward style and pair a two-toned striped top with matching pants and neutral suede pumps for a night out with the girls.

Stacy Keibler is the latest starlet to rock the new celeb-approved blue and orange color combo, donning a navy Tory Burch peacoat ($495) with sherbert orange skinny Joe's jeans while running errands in NYC. Stacy paired her fresh duo with a sheer-stripe sweater, cap-toe snakeskin flats, a neutral leather YSL hobo ($1,544) and oversize cat-eye shades.
