The sweeping black dress was very Audrey Hepburn-esque.

Blackpink's Rosé had a "Breakfast at Tiffany's" moment on the steps of the Metropolitan Museum of Art on Wednesday night. She is, after all, a Tiffany & Co. ambassador.

She's also a Sulwhasoo ambassador, which is why she was at the Met, to celebrate the Korean skin care brand's partnership with the museum. Rosé arrived in a black, floor-length gown by Choijaehoon — no voluminous updo or dainty cigarette holder, but the look still felt reminiscent of Audrey Hepburn's iconic look as Holly Golightly, only with a Blackpink twist (spaghetti straps, square neckline, velvet bow in the hair).

Rosé accessorized with — what else? — Tiffany & Co. jewelry. Her platinum and yellow gold diamond Bypass Bracelet retails for $69,000, while the matching necklace goes for $57,000.

She really was the belle of the ball.
