US museum criticized for allowing Kim Kardashian to wear Marilyn Monroe gown to Met Gala

A US museum is being criticized for allowing reality star Kim Kardashian to wear an iconic Marilyn Monroe gown to the Met Gala in May.

Monroe historians have revealed new photos of the damaged dress, which now has stretched fabric and missing crystals.

Its current owner, Ripley's Believe It or Not, is facing criticism for failing to properly care for the fragile gown.

Monroe wore it when she sang "Happy Birthday" to President Kennedy in 1962.

Ripley's bought the dress for $4.8 million in 2016, and it is now estimated to be worth more than $10 million.
