When Katie Holmes married Tom Cruise in 2006, she transformed from former Dawson’s Creek star into one of the most frequently photographed women in Hollywood. With the help of stylist Jeanne Yang (with whom she later co-founded a fashion line, Holmes & Yang, which now serves as the actress’s principle clothing source), Holmes turned her wholesome, casual wardrobe up a few notches. She soon became just as celebrated for her ballet flats and boyfriend jeans as she was for her sophisticated red carpet outfits, which range from sleek black jumpsuits to more conventional cocktail dresses. See her fashion highlights through the years.
