UGG boots are everywhere at the moment, and if you've ever wondered how to wear them, you don't need to look much further than the archive of iconic celebrity looks from the Noughties, including Sienna Miller's 2007 outing.
Although the classic chestnut shade is consistently favoured, Sienna made a convincing case for embracing the sleek black variation. The actress paired her black classic UGG boots with a black fur-lined jacket, skinny jeans, and another vintage classic, the Balenciaga City Bag.
If you're wondering how to style UGGs in 2026, we'd recommend that you take inspiration from this styling combination. With UGG boots firmly back on the agenda and skinny jeans resurfacing, this outfit has never felt more relevant.

Black UGG boots are a wardrobe investment that never ages. Unlike the classic chestnut shade that can feel seasonal, black pairs with nearly any outfit, from sleek all-black outfits to vibrant shades or patterns. Plus, the colour also resists visible dirt and scuffs better than lighter shades, too.
