Don't worry about what they think. Hold you head high, shoulders back and boobs out. If you don't pass then own the look - it's you. Have attitude because it will get you a lot further than looks anyday. Plus it doesn't fade with time.
That's good and bad. It will depend upon how much attitude I want to expose the world too. usually I don't mind being noticed but we may not be the weirdest thing in Vegas. So we may just have to admit that we are ordinary there. :D
