By Jenn HarrisSinger and actress Katy Perry is known more for her chart-topping hits than her sartorial ones, but she deserves kudos for her sense of style over the last couple of weeks.At the 2013 ASCAP “I Create Music” Expo in Hollywood, Perry donned a Suno spring 2013 dress with a cellphone print and accessorised with metallic sandals. At the Lacoste Coachella party, she chose a print Dolce & Gabbana skirt. And she wore a striped dress by the Italian fashion house to a news conference for her new film, The Smurfs 2, in Mexico.At the fifth annual Summer of Sony in Cancun, Perry attended a photo call for the film wearing a Monique Lhuillier spring 2013 lace dress that she cinched with a black belt. She finished the look with metallic Jimmy Choo “Anouk” pumps, a blue floral headpiece, blue earrings and Dolce & Gabbana blue-and-white striped cat-eye sunglasses.Flash back to The Smurfs premiere in 2011, when Perry had blonde locks and wore a corset from the Blonds with a picture of Smurfette across the front. What a difference now. For the new film, she may have taken the blue theme to an extreme, but each element was subtle enough for it to work.To get Perry’s look, try the Adrianna Papell scalloped lace dress from Nordstrom for $138.
