Our fave red carpet trend? Sharply tailored suits. A-listers are giving the gowns a rest and stepping out in mega-menswear inspired looks, and we dig it. The latest babe to give us suit-envy is Emma Watson, who stopped by Late Show with David Letterman last night rockin' Saint Laurent. The Saint Laurent suit is quickly becoming a serious cult item, with celeb fans including Angelina Jolie, Cara Delevingne and our ultimate hair crush, Mr. Jared Leto. Wanna work a suit to the max? Keep the accessories super simple—and tie it all together with a red lip. Boom! You're in the club now.
