Wow you make a lot of assumptions about the person in charge of making sure the dress code was adhered to. If being told to cover up a dress is all this girl ever has to contend with is her idea of a ruined night she should count her blessings.
Well you made the first assumption, that she knew she was breaking the rules. I contend that she knew no such thing because the dress is so old fashion and modest.
I’m betting my assumptions are closer to the truth than yours.
