Everybody seems to be making a big deal of Sansa’s hair - that we should be worried she’s morphing into Cersei because it’s the way she’s worn it in the past. A plausible theory, I have another:
What if Sansa has just become the sum of her experiences? In other words, her clothes, and her appearance are outward expressions of all of the meaningful things that have happened to her. She wears a cloak like her father’s, which she sewed the way her mother taught her, she sometimes wears her hair like Cersei or Maergery, or parted like the Northern women. Her cloak has a mini dagger on the chain (possibly like Arya's "Needle"), and a big circle on it, like the disguise she made when she travelled to the Vale with Littlefinger.
Yes, Sansa has learned a lot from Cersei (which may or may not be to her detriment). But she’s also learned from Ramsay. And Joffrey. AND Littlefinger, Tyrion, Shae, Maergery, Brienne, Theon, her father, mother, brothers, and sister, etc.
Sansa might have been one of the more malleable characters in the beginning, adopting the look and traits of the people whom she admired at the time, but her character has also grown more than most. I believe she’s become her own unique person, with influences of others incorporated here and there. We’re all a product of our experiences! I don’t think we should attribute her growth to just one person when so SO much has happened to her!
