What Should I Wear.... to Vegas Night?

I wish I could fill this post with a bunch of pictures of awesomely cute outfits, but alas, that won't be happening. Our country club is hosting a Vegas night next weekend, and I'm at a complete loss as to what to wear.

Not a freakin' clue.

Not really even an idea or an inspiration, other than I think bling should be involved.

HELP.
