Sienna Miller Looks Completely Different With Extra-Long Boho Waves

While we still love our impossibly voluminous blowouts, lower-maintenance haircuts have been trending for winter. From the resurgence of low-lift mermaid waves to trending crops like the grown-out pixie Tinkerbell cut, styles that feel intentional yet effortless are gaining popularity for every length.

Miller’s “fairy princess waves,” as British Vogue dubbed them, are especially romantic on extra-long hair. But anyone who can manage a few braids can easily get the look. To try it for yourself, let your hair air-dry almost completely before bed (and don’t forget to use a hair oil to lock in moisture and protection). Before you go to sleep, add two to four loose braids to your hair to create a crimped wavy texture. Don’t worry about keeping things tidy—different-size sections and nonuniform areas will help you emulate Miller’s natural final look.

In the morning, take out your braids, hit your hair with some dry texture spray or a sea salt mist, and loosely brush out your waves. With minimal fussing, you’ll have a new shortcut to “I woke up like this” hair for 2026.
