Does a lady have to wear a full length dress to a black tie ball?
Not Black Tie which is Dinner Jacket knee will do not a mini skirt A White Tie is penguin dress and very formal so there the answer is yes. In some ways this form of dress wipes out “class distinction” some of the wealthiest have the well worn JD and the poverty stricken like me in a hired one don’t look that bad These things are intended to be enjoyed just go and enjoy it you will be surprised how many have never been to one before. I went to my first one when in my 50’s and really enjoyed it in spite of the (pre show nerves) even though some of the men looked far better and confident than I have ever looked.or been.
