Last night on "Late Night With David Letterman," Eva Longoria shilled her new cookbook in a cute short and blazer set, and almost had a wardrobe malfunction of epic proportions when her blazer button accidentally popped open (and yes, Letterman couldn't keep his eyes off her chest). Them's the breaks when you wear a blazer sans shirt, we suppose. Still, we love the look and think Eva looks extra stylish here. We found a few other celebs who took businesswear to a sexy place with a blazer-minus-shirt combo. Check 'em out after the jump!
