With the holiday season fast approaching, it's time to start thinking about what you're going to wear to every event on your packed calendar. Sometimes, dark-wash jeans, a crisp tee, and some fun shoes will suffice—just add a pair of cascading earrings for some added formality. But others call for apparel of the more obviously festive variety, in which case, this is the dress color you'll want to go with. How do I know? Well, it's the shade you'll see every It girl wearing, with Sienna Miller donning it most recently. I'm talking about silver dresses, people, and if you don't already own one (or even two), now's the time to buy one.

Miller, who is currently starring in the series War across Dominic West, attended the 15th annual LACMA Art+Film Gala in Los Angeles last week, and chose a sheer, chainmail minidress by Gucci, one of the main sponsors of the event. It was silver, too, as all the best holiday-season dresses are. The actress accessorized with a black Gucci clutch and simple black pumps, letting the dress be the star of her ensemble.

Sure, the one-shoulder party dress wasn't technically worn for a holiday event, but that shouldn't stop you from taking her lead and opting for something metallic over the easier LBD for every cocktail hour, work soirée, and Friendsgiving celebration you're stopping by between now and the new year. Speaking of New Year's Eve, a silver dress is optimal for celebrating the end of 2026 and the start of a fresh 365-day palette.

Do I really need to convince you, though, that a silver dress is perfect for the holidays? Miller did that all on her own. Shop my favorite styles below.
