Perhaps my previous suggestion for Halloween, Lady Mary, wasn't necessarily your thing. Allow me to suggest Carrie Mathison. Although Carrie is super complex and complicated, her style is not. She wears classic lines and pieces. She seems like the type of chic who shops just once a year - but when she does she drops several grand on quality, designer duds.
If I was her, I'd be using my sleek wardrobe to seduce Saul, not Brody, because Saul is the shit. But that's just me. Happy Halloween friends!
