We can totally understand why Kiernan Shipka wants to steal Sally’s wardrobe this season. For her call with Don about the burglary, Sally wears a layered look consisting of a purple fair isle cardigan, blue collared shirt, a plaid A-line skirt, and her hair back in a clip. She looks like a little girl–in spite of the hell she raises later on in the episode.
When Don gets her from school and brings her (and her little brothers) to see his old (whore) house, she wears a plaid, Peter Pan collared swingcoat, penny loafers, and white knee socks–a little girl outfit if ever there was. She may have a fake ID, but Sally’s nowhere near as grown up as she thinks she is.
