debut party with Las Vegas theme...  

I will be attending a debut bash on Friday and this one has a Las Vegas theme or motif. I was also tasked to be one of the 18 treasures so that means I would need to go up the stage to give a short speech. I wonder though what would be a good outfit for such an occasion with such a theme. The color motif is sparkling red combined with silver. Can you guys give me some suggestions? I have an off-white blouse with some silver beads so I wonder what else should I mix it with to make my outfit look thematic. Thanks for your advise again guys.
