The only difference between what happens during Fashion Week and dressing up for Halloween is the degree of extremity. At its core, putting on clothes for fashion's sake is about dressing up as the person you want to be that day, whether it's "put-together person" or "don't-bother-me person" or "Parisian person by way of Iowa." Having great personal style is about possessing a clear idea of what you want and allowing yourself the freedom and creativity to explore that space. And, we all know that the best All Hallows' Eve costumes are clear and direct, but they're also delightfully unexpected, too. For one day a year, you can literally be anything you want, and for me, that thing is usually witty, silly, one-of-a-kind, and slightly nerdy. And, cheesy, usually (blame the puns). I once deviated into "sexy" territory as Skankhis Khan, but I wore a Fu Manchu mustache for good measure.
