In a new teaser video for her Diet Coke partnership, Swift talks about her deliberate effort over the years to "dress her age."
"I think one of the things I've always tried to do was age gracefully. It was what I was trying to do when I was 18 -- just be 18," she said. "I find it hilarious when I'm going to an award show, and I'm wearing shorts for a performance, and the next day the headlines are like 'Taylor goes edgy for her performance!' I'm like, 'I'm wearing more clothes than anyone here!'"
Watch the full interview in the video above.
Swift is releasing a behind-the-scenes video series that will be available on the start date for her Red tour, March 13, via Diet Coke's Facebook page.
