We love Sienna Miller's gorgeously flattering and versatile denim midi dress that's sure to become an autumn staple this season - her vampy styling with a leather trench coat and matching lace up boots was a stroke of genius.

Sienna Miller is a huge fan of denim and regularly steps out in impossibly cool denim styles, like barrel leg jeans and ultra-baggy styles, to give us the best casual-chic outfit inspiration out there.

While Sienna deviated from her usual boho style with this effortless and laid-back take on eveningwear, she couldn't leave behind her iconic long waves. Styling her hair in her usual middle parting, her healthy and glowing blonde strands cascaded around her face, with lots of volume at the roots creating a lovely flowing style.

For makeup, she kept her style ultra-natural, with a bold brow bringing dimension to her face while a natural nude lipstick shade added a subtle pop of pink to the look.

We love this pared back and simple look, with each element, from the footwear to the lipstick, working together to create a cohesive, wearable and fun style that we can't wait to recreate.
