Kim Kardashian allegedly damaged iconic Marilyn Monroe dress she wore on Met Gala red carpet

Kim Kardashian has been slammed online after reports she damaged the iconic Marilyn Monroe dress she wore to this year’s Met Gala.

Twitter account Pop Crave has published photos with a side-by-side comparison of the dress first worn by Monroe while singing “Happy Birthday, Mr President” to US President John F Kennedy in 1962.

“The dress now shows signs of tearing, and several crystals are either missing or hanging off of it,” part of the post reads.

The $6.7 million gown holds the record for the most expensive dress purchased at auction when it was bought by the Ripley’s Believe It Or Not! Museum for $US4.81 million, AUD $6.7 million, in 2016.

Last month, the designer Bob Mackie, who drew the sketch for the original gown, said that Kardashian wearing Monroe’s dress was a big mistake.

“(Marilyn) was a goddess. A crazy goddess, but a goddess. She was just fabulous. Nobody photographs like that. And it was done for her. It was designed for her,” he argued.

“Nobody else should be seen in that dress,” he told Entertainment Weekly.

Ripley’s — which loaned Kardashian the look to the star— is currently displaying the garment at its Hollywood location.

They previously denied there was any damage to the dress.

“This was no easy decision for Ripley’s, however, Kim Kardashian has continued to show the utmost respect for this opportunity and historic garment,” Ripley’s said in a post-gala statement.

“From extensive research to following guidelines such as no body makeup, only wearing the dress for the short red-carpet appearance, and making absolutely no alterations, she has become a steward — and added to — its history.”

Kardashian reportedly lost 7kgs in three weeks to fit into the dress.
