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.

Celebrity Style: Rihanna
Rihanna has been getting increasingly experimental with her street style lately. The sassy singer went to Derek Lam's store opening in NYC last night wearing a white Bianca Jaggeresque pantsuit that many cannot pull off. To prevent looking too businessy, Rihanna paired her Lam suit with a sheer animal-print blouse, retro sunglasses, tons of gold jewels, a Jimmy Choo clutch, and metallic platform pumps. It looks like the streaks she had at the Met Gala have gone way chunkier. Love it all, from her head to toes.

Lighten Up: Pantsuits Are Creepy
OK, consider this your warning: this video will freak you out. At least it gave me shivers. Perhaps this means that pantsuits are not actually universally flattering?

Go ahead and watch it, and then please tell me — which Clinton do you think wears the pantsuit? Which kid got to you? Whatever you do, don't cross the "did you get your pantsuit at Wal-mart?" kid!
