Taylor Swift first walked a red carpet in 2006 when she was just 16 years old. Just take a second to absorb that info. Now at 29 (she's turning the big 3-0 on Dec. 13), she's had quite the style transformation over the years. (She's also weathered public romances, celebrity feuds, that "I'mma let you finish" moment, and countless other controversies and life events.) From her country days wearing cowboy boots with minis to her sparkly pop queen looks, there's a LOT of fashion to unpack. Here are a whopping 150 photos to take you through (almost) all the outfits she's worn through the last decade.
