“In the last film, the hair and makeup team and I discussed what would’ve happened to her visually when she went through the fire. And there was this sense when she went through it, that something of her had been burned out of her, that it was painful crossing through. So visually we explored sort of the loss of pigmentation in her hair that she used to have this very warm, rosy, curl mop. And when she came through the fire, it became much more sleek, much more contained and colorless. And as far as costumes, Colleen broadened her into a much more sophisticated, more sort of contained look to the dresses as well. It is dark obviously, but there’s mystery in it. And we wanted to reflect that in everything that she wore.”
