Seriously: Your outfit could be totally mediocre, and all of a sudden, with your jacket falling off just so, it'll look like you tried less (and yes, that's a good thing these days). Remember that "rule" that says to always take one thing off before you walk out the door? Well, we're taking it and flipping it on its head. Next time you get dressed, take one piece half off. And if it looks like an accident, well, you're doing it right.
