Nicole Kidman rewears Chanel dress from her famous 2004 perfume ad on the Met Gala red carpet

Nicole Kidman hasn't failed to impress on the Met Gala red carpet – and there's a reason her dress looks so familiar.

Attending the event with husband Keith Urban, the Aussie star is wearing a Chanel dress she previously wore in a 2004 advertising campaign for the fashion house's famous No5 perfume, directed by Baz Luhrmann, titled Le Film.

Looking stunning in the pale pink Chanel gown, the 55-year-old is followed by an impressive four-metre train, crafted from silk tulle and embroidered with pink ostrich feathers and sequins.

Kidman teased fans prior to her arrival at the Met Gala, posting a clip of the 2004 ad campaign to her Instagram, captioning the post "Running to the MET".

While fans were excited to see the actress hit the red carpet, not many expected she would literally be rewearing the 2004 gown.

Kidman shared a second post with the other half of the commercial and captioned it "For Karl".

This is a nod to the Met Gala's theme for 2023, which is "Karl Lagerfeld: A Line of Beauty".

Attendees are commemorating the late fashion designer and creative director of Chanel through their fashion, and it's clear Kidman found a unique, vintage way to honour Lagerfeld.
