I bought the Settlement Ambush Kit from creation club, and the settlers well change back to there original clothes you found them in, even they'll you removed all there old clothes and gave them new clothes when they use the gun range if the Settlement Ambush Kit from creation club So I thought the only way they'd be able to fix this is by ways of a doorway the walk through that changes there outfits!.. So you'd have varies doorways for each building, the sleep quarters would have sleep wear, the swimming pool would have no clothes or swim wear, the greenhouse would give work wear, if you made a dance hall or bar, there evening wear etc
