Mrs. Mills does dinner

What to wear, what to wear? Mrs. Mills provides the answer.

Is there a difference in dress code between a formal and an informal family dinner? Would a miniskirt or mid-thigh-length skirt be appropriate attire?

I personally thought this question had been answered in the 1970s.

It depends on age and, to some extent, gender. However, generally speaking, there is no difference: you can wear what you want, until the most senior family member objects, either verbally or physically (vomiting, heart attack and so on).
