Los Angeles, California - Pop icon Ariana Grande stunned in old-school Hollywood vibes on Tuesday night at the Academy Awards nominee dinner, and fans are gawking over her fashionable look!

The 31-year-old superstar brought her fashion A-game to the event with a vintage black bow-detailed Yves Saint Laurent gown, complete with a chic pink feathery neckline.

But this isn't just any gown – it's a piece of fashion history!

First hitting the runway in 1991, the iconic dress made its Oscars debut two years later on French legend Catherine Deneuve, per Page Six.
