We know that Katy Perry is capable of just about anything when it comes to red-carpet dressing — remember last year's quartet of zany outfit changes? That's why we were pleasantly surprised to find the brunette beauty in serious bombshell mode. From its gathered leather bow-tie bustier and delicate sequin embellishments to its sheer skirt, her dark, floor-skimming Elie Saab gown proved utterly romantic. To keep with the theme of all-out prettiness, Katy kept her accessories minimal, her makeup light, and her black tresses loose and wavy. Do you prefer this feminine look to her more outrageous ones?
