“if my girls want to wear a longer skirt with short socks that cover the ankle in the summer and most other girls are doing that also, it would be foolish to disallow it and be makpid.”
Hate to break it to you. But all too often the legs become easily exposed with such a combination. Any slight move can expose the uncovered leg. It doesn’t matter what most other girls are doing. Even knee socks under a long skirt (long skirt i mean till floor/ankles)can be problematic.
