When “Call Me Maybe” singer Carly Rae Jepsen needs an outfit, she definitely calls stylist Lauren Shane, no maybes about it. “She’s my stylist and one of my really good friends,” the singer told InStyle.com recently. “She’s my match made in heaven. She shows up and it’s one less stress for me. It’s always my size and something that I love. I’m lucky to have her.” So, for last night’s Teen Choice Awards, Shane dressed the 26-year-old in two playful California girl looks—a palm tree print Lisa Ho blazer and shorts for the red carpet and a polka-dot Ani Lee romper accessorized with an oversize bicycle charm necklace for her live performance. “The one rule we have is that you’ve got to feel comfortable,” Jepsen said of her style. “You’ve got to have fun with it and not be afraid to try new things.” Watch her sing her hit single above, complete with celebrity and fan renditions playing in the background.
