Except for (maybe) George Clooney, the nominees for Best Actor at this year's Oscars aren't known for playing it safe on the red carpet. From Daniel Day-Lewis's preference for tiny suits to Viggo Mortensen's disdain for anything bland, we're not accustomed to seeing plain penguin tuxes from this group. But judging from their track records, they all have ways of showing their true colors without actually wearing them all at once. So we reviewed their greatest hits and greatest misses to figure out which way they should swing on Sunday.

The question on the minds of the glossy mags isn't who will take home little gold men on Sunday night, but rather who'll make the biggest fashion faux-pas. And there's no shortage of mistakes made by this year's Best Actress nominees in the past. But we aren't hoping for new additions to the Fashion Police Hall of Fame; instead, we went digging through the archives to find the biggest mistake all five actresses tend to make in the style department, and our suggestions for which signature looks they should keep in mind to achieve sartorial success come Sunday.
