Katy Perry may not know it yet, but we're pretty sure she's found her signature color. From the lilac lace one shoulder Elie Saab gown she wore to the premiere of husband Russell Brand's new movie Tempest, the plum satin and lace dress by Zuhair Murad worn to the Jingle Ball, and finally the satin Miu Miu dress she wore to her fragrance launch, Katy proves she looks great in all hues of purple.
