My friend and I are going to brunch, then going to the ballet at the Kennedy Center this afternoon. The last time I attended the ballet was in February right after work so I had a dress on. The sad thing is that 70% of people there were casual including jeans. Knowing me, I choose not to wear jeans. My friend is wearing a LBD (I'm assuming she meant ??? black dress) which is odd for the day. Any suggestion for me?
