What Was She Thinking???

Katy Perry is known for her outrageous sense of style...but there is something about this look that is just a little too much for me to handle. I know she's in Vegas and she wanted to be quirky...so a card dress seemed like the likely solution. I get that. But I think my biggest problem is the headband! Eeeekk!!!

What do you think of her look? Is it unique and fun, or totally tacky? We want to hear what you think!
