I remember in grade school the girls were not allowed to wear jeans or slacks. We had to play basketball, baseball etc in a dress. Then the new principal decided we could were jeans on Friday's......which was free play day....lol
My Mom always made sure we were presentable when we went out in public. Even our play clothes all matched. I made sure my kids did the same and they do now for their own kids.
I make sure I look decent when we go out, I even "gussy up"( nice shirt or blouse and maybe even a skirt) a bit when we go out to dinner.
