She's not as strict because clothes washing in the snowy mountains is probably really hard, but she does make them have some sort of hygienic routine at least once a week. I actually read a giant ass article about how hygiene worked back then, and because of the clothes we wear today, and not layering them, we sweat a lot more and smell a lot easier. Back then, people would have undershirts that were really light and often changed out, and the material isolated smell more. Also being outside and especially around campfires would mask any smell on top of it. They had things like powdered deodorants and such. So there are things they can do without needing to outright bathe constantly, and I think as long as they're changing out their underclothes regularly and powdering themselves and brushing their teeth enough, she's satisfied.

The goons she's very distant towards (usually further from the cabin, like the little camp that leads up towards the mountain in the last mission wayy before you get to the cabin?) she'd care less about them. They're horrible to talk to, don't listen to her, but at least keep their distance.

Now she herself will beg Micah to take her to town so she can bathe every few days. She's a diva who can't stand feeling too unclean. Needs that royal bath treatment. And if he doesn't agree, she will make it his problem.
