Worst-Dressed List: Mary-Kate Olsen & Linda Evangelista Fail At Volume (PHOTOS)

The reason that most stars landed on this week's worst-dressed list was because of bad proportions. Specifically, wearing ensembles that were too long, too loose and too voluminous. Celebs like Mary-Kate Olsen and Linda Evangelista were lost in their dresses, proving that even designers and models can't pull off tricky volume. A belt would have worked wonders.

Though this week was a full of sartorial missteps, Jennifer Lopez's tight leather dress (complete with a plunging neckline) takes the cake for the most outrageous look -- leather in June just doesn't make sense.

Check out those over-the-top looks, as well as more celebrities who made our week's worst-dressed list. Do you agree with us?
