I don't remember the rule about the nice pants, but I do remember that once you got the gown you could wear whatever you wished under it, as that stood as your dress code. But, alas, by the time I got mine (Advent semester Junior year), the dress code was such a habit that I was stuck. I did wear inappropriate clothing under my choir vestments, though. Ah, the memories.

And thanks for letting everyone know how old we are. For the record, you will always be older, my dearest friend. ;-) Although we are both glorious in our mid-thirties-ness!
