I'm here for the kids not the parents. The kids don't care if my top and pants clash or not or even if it is on backwards as long as they get their snack and favourite story read. I mean really - this is our home and we can wear what we want when we want and comb our hair only if we want etc. We get so few perks in this business we gotta take them where we can.
Maybe just a polite sorry mamm I don't work for you - your company dress code doesn't apply here. We wear play clothes.
