Hi Chuck and Valerie wonderful to see you post - welcome to the boards. This is a great couple everyone so glad to have them here.
JanR -- formal nights for me -- means the same black pants and shell and just a top that has a couple of sequins on it that I might also wear on casual night. It seldom makes any difference in what I chose to wear, formal, informal or casual.
You do not need to dress up to the nines if you do not wish to do so.
