Jennifer Aniston, 2003
''Jennifer was looking for something hot and sexy,'' Elizabeth Mason of L.A.'s Paper Bag Princess boutique said of the normally demure Aniston's decision to wear a cleavage-baring 1970s vintage Halston halter dress. Though then-husband Brad Pitt was away filming in Mexico, the Friends star had a cheeky way of keeping him close as she walked the red carpet. ''I actually have a picture of him... on my underwear,'' Aniston told People.

Blake Lively, 2009
This is what we in the industry call a game-changing fashion moment. When the Gossip Girl star stopped to strike a pose in her crimson Versace dress — which featured a dangerously low plunging neckline and back line, and a hip-high front slit — jaws dropped, heads turned, necks craned, and though she wasn't even nominated, her name was suddenly on everyone's lips.

''I went to Giorgio Armani, they put this on me, and I said, 'Fine, hem it and I'll get out of here,'' the Seinfeld star told reporters of her cut way-way-down-to-there dress on the red carpet.
