This week, I said that to DD2 because she had worn the same the day before and it was covered in stains that I'm not sure how she thought she should go out like that.
I used to repeatedly tell DS2 he can't go out unless he puts trousers on the fit him and by fit, I mean he can jump up and down and no one sees his underwear/have them fall down (we had a bit where he would pull his siblings' old clothes out to wear even when they didn't fit him. Now I store any hand-me-down clothes out of his reach.)
So yeah, my main 'you have to get change' involve them being dirty and if I can see their underwear. I have made a child add additional layer for underwear lines & similar mostly because I know that previous comments on that by others caused upset though it's been a learning process on clothes to figure out what will and won't be an issue.
Makeup I'm not bothered by, but the only makeup my kids own was either given to them as gifts by others or bought with their own pocket money which may be part of why they're so careful with it and only use it with friends rather than to go out.
