Sienna Miller proved high street can look so expensive as she wore head-to-toe M&S in crisp white suit with animal print clutch

Sienna Miller is seen leaving Louie restaurant on October 29, 2024 in London, England.

Sienna Miller showed that you don't have to splash out on high end labels and extortionately pricey pieces in order to channel serious sophistication, going head-to-toe high street in the most gorgeous M&S pieces.

While Sienna's wardrobe is jam-packed full of designer names and items with price tags most of us can only dream of being able to shop, she doesn't always opt for the likes of Chloé and Louis Vuitton whens she steps out for special nights.
