Quel Scandale! Reese's used gown, Mariah's scary couture — Chanel's major fashion faux pas

Move over. Armani. Chanel made the bigger splash on the red carpet at Monday's Golden Globe awards. Chanel dresses were spotted on hot young actresses Reese Witherspoon, Emily Mortimer, Natalie Portman and Vanessa Paradis as they strolled the red carpet.

But the House of Coco also made a couple of serious fashion faux pas.

Mariah Carey wore a gown especially designed for her by Chanel's Karl Lagerfeld — a skintight plunging neckline crystal-splattered gown that looked more Mae West than Maison Chanel.

So why was Carey's name was left off of Chanel's press release? "Was it left off?," asked Gretchen Gunlocke-Fenton in Chanel's New York fashion public relations office. "That could have been because we're never sure what the actresses will wear until the last minute. And she had several fittings in Los Angeles after she met personally with Karl in Paris."

Oh-kay.

And many in the fashion world are wondering why Witherspoon ended up in a Chanel gown previously worn (horrors!) by Kirsten Dunst. Reportedly, Witherspoon was excited to wear a "vintage" gown by her favorite designer, thinking that "vintage" meant a classic frock worn in some bygone era. She had no idea it was a Dunst redux.

It was only after the Globes that Witherspoon's camp learned the dress was worn by Dunst to a 2003 Golden Globe Awards party, with her hair done just like Witherspoon's. Yikes.

Chanel issued this statement: "Chanel apologizes for the oversight that Reese Witherspoon's dress was previously worn to a Golden Globes after party three years ago. We are honored that Reese chose to wear Chanel and thought she looked beautiful. We congratulate her on her well-deserved win."

Witherspoon's publicist, Nancy Ryder, has told reporters that she and her other clients will boycott Chanel. And other star's stylists are horrified that this duplication occurred.

"A star in the best actress category should never be seen in a dress that's been seen before anywhere, even on the runway," sniffed a top L.A. fashion PR gal. "Most actresses today insist on a couture gown especially made for them."

But considering Carey's cheesy couture creation, maybe Witherspoon was lucky.
