Malin Akerman, Joy Bryant, Rachel Bilson and Jessica Lowndes proved you don’t have to break the bank to look sexy-chic for a night out.  The foursome hit TAO in Las Vegas over the weekend to celebrate Express’s new ReRock denim, each wearing something under $100 from the brand’s new spring collection. Akerman worked a gold bandage minidress ($80, available in stores), while Bryant wore a tiered black dress ($70) paired with an edgy motorcycle jacket ($98, available in stores).  Bilson rocked a ruffled two-toned jumper ($70), and Lowdes showed off new light wash ReRock skinny jeans ($80).
