Actress Reese Witherspoon was named People magazine's best-dressed person of 2015 on Wednesday. Witherspoon, the Oscar-winning star of Johnny Cash movie "Walk the Line," headed a list that includes Hollywood stars Julianne Moore, Kate Hudson, and 15-year-old "Mad Men" actress Kiernan Shipka. Witherspoon ironically was one of the women leading an #AskHerMore campaign at the 2015 Oscars ceremony in which reporters were encouraged to ask actresses on the red carpet more about their work in movies than their style choices.
