8 Ways Hollywood Changed Fashion

Fashionistas rejoice: Mad Men returns tonight! To celebrate the show's influence on fashion—yes, thin-lapelled suits and Peter Pan collars are back—CNN remembers other Hollywood offerings that dominated the fashion zeitgeist:

• Jennifer Beals cut the collar off a sweatshirt only to get it over her head, but her accidental off-the-shoulder look in Flashdance made active wear look sexy.
• What’s a list about Hollywood fashion without Sex and the City goddess Carrie Bradshaw? Simply put: She shopped, and a nation swooned.
