Celebrities are trading in their jeans for this season's must-have cargo pant and their favorite pair is J Brand's ultra-skinny Houlihan (I must confess that even I am wearing the cult pant as I write this!). The great thing about these pants—besides their incredibly comfortable fit—is that they look chic with flats, but dress up instantly with a pair of sexy heels. Rihanna, Rachel Bilson and Jessica Alba worked their Houlihans with pumps, peep-toes and platforms while on-the-go mom Gwen Stefani stylishly sported hers with flip-flops. You really can't go wrong with these versatile pants! Snag yourself a pair at jbrandjeans.com.
