Quick opinion needed

In recognition of National Freedom to Marry week, Outlaws is throwing a party tomorrow night.  In order to advertise the party, we are all supposed to dress up in wedding clothes.  Unlike the last time, when we all screwed up the communication, this time we are all really supposed to dress up! :)

I am torn between my dual natural inclinations to a) look as pretty as I am able and b) screw with people's minds and their stereotypes.  I have the clothing, I believe, that would be apropos of either.  I could wear a very beautiful dress that I wore as a bridesmaid, or I could wear a tuxedo that I once wore as a groom.  What do you think?

[Update]  Thanks for the opinions.  I opted for the tux.  I haven't had this many people openly stare at me since I first came out.  Weird.  But, it is effective!  I'll post a photo later, if we manage to get one.

[Update 2]  OK, so I decided to do boy drag today -- the picture is of a classmate and me -- and girl drag tonight.  This should satisfy everyone -- including the other classmate who earlier today told me that she was rooting for the bridesmaid dress -- my mother (whom I know was rooting for the dress, despite her silence),  and me. :)

[Update 3 - Final] What a GREAT party we had!!!  A very nice turnout of people.  We had balloons and cake and champagne.  It was so much fun, even for a Tuesday night!  As you can tell from this photo, I'm not doing as well on my diet as I wanted. ::sigh::
