Keira Knightley vs. Olivia Munn: How Not to Dress for a Late Show

Two late-night looks, one frumpy and one hot, but there can only be one winner in the midnight showdown!

What is it about a late-night talk show that makes starlets reach for their tightest, shortest dress?

When Amy Adams showed up to David Letterman in August, she suddenly decided it was a fine time to channel her inner Courtney Stodden. And people like Eva Longoria and Lea Michele have done the late-night thing in dresses so tight you can see their ribs. From the inside.

Here's the opposite of tight: ScarJo's pants

Then again, it could be worse.

Observe Keira Knightley as she arrives at Late Night With Jimmy Fallon, fresh from her day job as Mayberry's favorite lovelorn librarian. Now see Olivia Munn, who's practically in uniform as she struts in to visit Jay Leno. (The uniform being equal parts hot, hot and hot.)

Unless there's maybe something we're missing?
