In other words, try hard but look like you haven't. Like really haven't. Does your t-shirt come with a $5,000 price tag? Excellent! Is it basically just plain white and slightly destroyed on top of that? Even better! Your hair should cost as much as your Jimmy Choo Belgravias (that's right, you're cool enough to party in high tops), but it's fine if you found your current jewelry in your neighbor's trash.
