Gwyneth Paltrow Is 2012's Best-Dressed Actress For Many Reasons (PHOTOS)

It's no surprise that Gwyneth Paltrow was named People Magazine's most stylish woman of 2012.The GOOP founder, mother of two and "Avengers" actress is often spotted on our weekly best-dressed lists.

But, her fashion sense isn't anything new. The Hugo Boss model (and wife of Coldplay frontman Chris Martin) has been a style icon since she started acting in 1990.
