For a second, just before the VMAs, Erin Wasson thought, "Hm, maybe I'm trying a little TOO hard to be SEXY." Then she decided, no, definitely not. This is exactly the right level of sexy. You know, short of twerking in latex undies with a bunch of people in bear suits as backup dancers.
Of course, holding this red carpet pose for too long means a few trips to the chiropractor, but it's all worth it.
