People magazine executive editor Elizabeth Sporkin commented: "There has been a trend this year in lady-like fashion, and I think she is almost single-handedly responsible for it."
In response to the acccolade, Washington said: "I don't wear a lot of pants. When I go somewhere I want to know I'm going to be comfortable and I'm dressed for the event."
It isn't the first time Washington has been lauded for her fashion sense. She lead Vanity Fair magazine's best dressed list over the summer. The magazine praised her for wearing stunning ensembles from Peter Pilotto, Miu Miu, Giles and Louis Vuitton.
