hell, there was a guy and grrl in my class at graduation who showed up wearing the standard cap and gown...and nothing else! totally bare under the robe (no shoes either) and it was a breezy day. this was at a lutheran high school and 30-some years ago...they still received their diploma's but were escorted from the line as soon as the powers-that-be found out and instead of getting them with us they had to wait for the mail...
