Many years ago I attended a concert (conducted by [now Sir] Simon Rattle at University before going to a fancy dress party at another University not very miles farther upriver so I wore my fancy dress (most of that of a bunny girl) under my suit. I have rarely been as prolongedly itchy in my life wearing tights and a leotard, sitting through the concert, as my leg and body hair was incredibly uncomfortable. I put on my powder puff tail, collar and cuffs and bunny ears later on together with high heels, borrowed from my then girlfriend. Let us hope that these girls costumes are not quite as uncomfortable but to a lesser degree (no pun intended) and they wish to shed them later in the evening.
Wow, I must have shocked you all as no reply for a full minute! I assure you all that that was the only occasion I have cross dressed in my adult life!
