Comic-Con is next weekend, and in honor of all things related to graphic novels, we’ve decided this entire week will be dedicated to the best-dressed superheroes, friends, lovers and alter-egos. This “Look-of-the-Day” is Scarlett Johansson in Iron Man 2 as Natasha Romanoff, better known as the Black Widow, who is one of The Avengers (wait for that star-studded film to come out in 2012!) Although Natasha began her life as a Soviet spy in the comic books, Scarlett plays an Americanized version acting as Tony Stark’s assistant in this atrocious sequel. Here, she’s wearing the sexiest secretary gear one can find – tight pencil skirt, black stiletto pumps and a form-fitting, busty button blouse. We’d hate to be Gwyneth Paltrow as washed-out Pepper Potts standing next to this pint-size sexpot!
