Asked who her style icon is, she said: "So many. Ingrid Bergman & the way Kate Moss dresses & the Duchess of Cambridge."
The actress is best known for playing stylist Carrie Bradshaw in 'Sex and the City' and revealed her favorite outfit she ever wore on the program was a tutu.
Asked for her favorite Carrie outfit in a twitter webchat for Glamour magazine, she said: "The tutu in Paris. It was a real tutu & I'm sure it was from the Royal Ballet."

The 46-year-old star also admitted she would like to venture into fashion design again.
Asked if she would consider another clothing line, she replied: "Definitely if I can figure out what it is I want to do."
