Actress Sienna Miller was seen attended the Proenza Schouler show during New York Fashion Week alongside her daughter. Sienna, 40, brought her 10 year old mini-me daughter Marlowe Sturridge with her to the star-studded wee-long event where they attended the Proenza Schouler show. Despite her young age, Marlowe looked like she belonged as she wore a grey blazer and three quarter length slacks, finishing the look with some black rectangular frame sunglasses.
