New York: The vintage Dior gown worn by Natalie Portman at the Oscars this year has fetched USD 50,000 at an auction.

The red polka dot haute couture creation, designed by Christian Dior in 1954, was borrowed by the 30-year-old star from fashion dealer Rare Vintage.

Shortly after the award ceremony, the vendor put the size 4 gown on sale via the website 1stdibs.com and it was snapped up by an unknown British couture collector, a leading daily reported.

Her look was created by top stylist Kate Young, who works closely with Rare Vintage owner Juliana Carione.

"Natalie's dress is amazing. It's an actual 1954 spring couture dress. She was actually going to wear another dress but then I got a call from the woman at Rare Vintage and she was like, 'You should see this dress for Natalie'.

"So we went and she put it on, and it needed zero alterations, and Natalie was like, "This was meant to be, wasn't it?" And I said, 'I guess it was'."

Dior, who died in 1957, was famous for inventing what became known as the New Look in 1947, and Portman's dress is typical of that.
