Sienna Miller’s Summer Capsule Wardrobe Centres Around 6 Timeless Staples

If anyone has mastered the art of summer dressing, it’s Sienna Miller. Long known for her bohemian-leaning style, she’s the kind of dresser who manages to look impossibly put-together while also giving the impression she didn’t try too hard—and that’s precisely what makes her so compelling.

This summer, her wardrobe feels especially distilled: a tight edit of core pieces that she’s been rewearing on repeat, often styled with nothing more than a pair of sunglasses and that signature tousled hair. The colours are soft, the shapes relaxed, and the vibe unmistakably Miller—cool, comfortable, and quietly romantic.
