Christina Perri blew up the charts last year with her Twilight track "A Thousand Years," and her momentum isn't slowing down. Currently, she's the opening act of Jason Mraz's national Tour Is A Four Letter Word, and she packed plenty of easy-to-wear pieces for her trip across the USA. "I love flowing dresses and maxis, which are perfect for a summer tour," the singer told InStyle.com. "My favorites are Topshop, Urban Outfitters, and H&M. It's absolutely perfect. It's all I wear." One of her favorite dresses is Topshop's black maxi with a floral mesh backing, which she wore on the Today show and in blue for her performance at Jones Beach in New York.
