Oh gosh, I hear ya. I attended a memorial at the KH last week, and had to pull a skirt out of the back recesses of my closet!! Then oy the garments I had to layer on! I dress professional every day for work...I would have looked perfectly fine in trousers. I wore the skirt because I just didn't want the pants to be an issue; I wanted the day to be only about the person who had passed.
It's a stupid rule by a stupid organization.
