Sienna Miller (born 28 December 1981) is celebrated for her relaxed boho-chic aesthetic, combining effortless glamour with Downtown edge. Key components of her signature look include:

  • Neutral basics: slim jeans, fitted tees, slouchy sweaters—simple staples form the base.

  • Bohemian layers: pieces like paisley blouses, crochet vests, floppy hats, lace tops, and cowboy-style boots.

  • Outerwear flair: timeless trench coats, often layered casually.

  • Statement accessories: oversized sunglasses, gold hoops, Western boots—all of which bring a personalized edge.

  • High-low mix: Miller often balances high-street finds, thrift/vintage, and occasional designer items (roughly 40% high-street, 40% vintage, 20% designer).

How to Build This Wardrobe on a Budget:

  1. Start with neutral basics: high-street jeans or plain knitwear.

  2. Add one boho piece: e.g., a printed blouse or dress.

  3. Top it off with a trench coat.

  4. Throw in Western-inspired footwear.

  5. Accessorize boldly: sunglasses, gold hoops, perhaps minimalist leather belts.
