Sarah Jessica Parker & James: School Days

Sarah Jessica Parker and her 7-year-old son James Wilke looked ready for the weather in their warm coats and winter boots as they headed to school in New York this morning (March 1).

The entrepreneurial mom-of-three - twin daughters Tabitha and Marion are 7 months - recently unveiled a new Sex and the City-inspired scent.

What I really wanted to do was capture an image, a snapshot in my head of Carrie Bradshaw," she tells People. "That sort of freeze-frame of her walking down any New York City street at an idyllic time of year in a floral-print dress on her way to meet somebody or to do something, or surrounded by her women friends."
