Photos of Sienna Miller and Savannah Miller Shopping in London

Sienna Miller embarked on day two of her shopping tour of London yesterday, though this time she brought her sister Savannah and a pal along for the trip. She was flaunting her Style Icon status in a pair of Kate Bosworth-approved red Chloe ankle boots as her trio made their way between stores. Life isn't all about hitting boutiques for Sienna, as she just participated in a charity photo shoot to benefit UNICEF. It's a way to combine her love for both fashion and philanthropy, and she could use a little damage control after the whole Balthazar fiasco.
