There is a dress code for a funeral, as there is for a wedding, a job interview, an audience with the queen or attending Ascot. In more formal settings, it’s called a uniform. A light shawl at a funeral or in a religious building would be the answer to the “but what if she (load of excuses)”. Just as I can’t bear to be presented with the builder’s crack, I really can’t bear cleavage on show in certain settings, while I admire them at weddings and less formal situations.
So the short answer is – it’s impolite to deviate from the dress code whether expressed or otherwise.
Dress codes change though.
At one point the “dress code” was to wear mourning colours for a year.
Time moves on. Traditions change.
