After award shows, it's always fun to look at the red carpet fashions and divide up the looks into "Best" and "Worst" categories. But at Sunday's MTV Movie Awards, the stars didn't give us much we could file under "Best." Yeah, it's MTV and it's summer, so wild looks and short skirts are to be expected, but the garish colors and unflattering designs would be out of place any time, any where. So we may have to grade on a curve.
