I was thinking it was kind of weird (and a little gross) to have colonists always in the same clothes, day and night, until they became tattered enough to give a mood debuff. Aren't there any mods that give colonists a personal "wardrobe" where they can store assigned clothing for different situations? Like something as simple as putting on different clothes before bed, as if they were pajamas.
Change dresser allows you to assign outfits. Not so much pj's for bed tho. They will switch for combat, work, and not sure but maybe a custom outfit. Its kinda cheatish cuz they hold a very very large amount of cloths. I use it tho. F**k physics!
