In a cute but conservative outfit, SJP sprinted down the snowy streets while playing the character of working mum Kate Reddy. The comedy, originally a book by Brit author Allison Pearson, follows the juggling act that is Kate’s life as a career woman and mum of two children.

A workwear ensemble of pretty blouse and pencil skirt were worn under a classic tailored winter coat and teamed with on-trend leopard print heels and Mulberry’s Alexa handbag.
