Dove Cameron showed up on the Upper East Side last night dressed like she’d stepped out of a whispered New York fashion myth. Instead of chasing trends, she borrowed a page from one of the neighborhood’s most beloved style characters: Blair Waldorf. Not in a literal costume way, but in that subtle, knowing way people who truly understand fashion can pull off.

The setting was Valentino’s dinner at Chez Fifi, a place where everyone looks like they belong in a mood board. Cameron arrived in a grey plaid two-piece suit that felt equal parts prep school nostalgia and grown-woman polish. The skirt skimmed above the knee, while the jacket softened its sharp shoulders with draped lapels. It was the kind of look that doesn’t scream for attention but ends up getting it anyway.

She was there among a crowd of cool-girl regulars — Charlotte Lawrence, Hari Nef, Sky Ferreira, Meadow Walker — all celebrating the Valentino Garavani DeVain bag. Yet Cameron’s outfit was the one that felt most in conversation with the evening. She didn’t go full country club. Instead, she styled the suit with clever touches that kept things playful: blue eyeshadow, a matching pussy-bow blouse, bow-detailed heels, and lace stockings. A lesson in how to keep preppy from feeling predictable.

Then came the DeVain bag. A soft, baguette-like shape covered in multicolor paillettes, almost glittering enough to earn a nod from another Manhattan fashion heroine: Carrie Bradshaw. If Blair gives you polish, Carrie gives you whimsy. Cameron managed to nod to both in one look.

Two New York icons. One outfit that understands the assignment.
