Even without the bright auburn hair or the intricately woven braids, Sophie Turner is still very much her: Sansa Stark, the cunning, tenacious Lady of Winterfell (and one of last two surviving Stark children — unless you count Bran, and we don’t) on HBO's Game of Thrones. The role (and the defining red hue) has been part of the star's life since the age of 13, and although she may be back to her natural blond color now, its significance still remains.
