I do think that you ignored, or at least minimized, one vital part of the discussion. - Brandon Sanderson

Jasnah hadn’t cared what people thought of her, yet had always kept her appearance immaculate. Not that Jasnah had acted alluringly—never for a moment. In fact, she’d disparaged such behavior in no uncertain terms. Using a fetching face to make men do as you wish is no different from a man using muscle to force a woman to his will, she’d said. Both are base, and both will fail a person as they age.
No, Jasnah had not approved of seduction as a tool. However, people responded differently to those who looked in control of themselves.

Dalinar would have said that the outfits looked silly, but sometimes fashion was silly.

You see the great thing about madness is that it's all in your head.
