Just a day prior it was revealed that Kim was unable to zip up the iconic Marilyn Monroe dress that she wore to Monday’s Met Gala, and was forced to leave it open, covering up her backside with a white fur shawl.

In a video from Ripley’s Believe It or Not! museum where she borrowed the gown, Kim is seen panicking as her team struggle to get the outfit over her famously large derriere. 

But despite not being able to fully zip it up, Kim was relieved when they realised they could just tie the back of the dress and then cover the rear view with a white fur shawl, similar to what Marilyn was known for wearing.

‘Oh my god! Yeah, can we use that tie and tie it, and keep it open?’ Kim asks when she sees that the dress just about fits, in a video obtained by TMZ. ‘The tie comes with it right? What if we did that and then put a fur over it. 

That meant that Kim wore the dress unzipped while she walked the red carpet of the Met Gala, before changing into a replica of the dress once she was inside the venue. 

The 41-year-old reality star revealed she forced herself to lose 16lbs in just three weeks in order to make it fit.

Behind the scenes: Ripley’s Believe It or Not! shared footage of the reality star trying on the dress for the first time 

Marilyn’s glittering beaded gown was designed by Jean Louis, and has been on display at Ripley’s Believe It or Not! Museum in Orlando, FL, after they bought it from Julien’s Auction for $4.81million. 

Marilyn – who died at 36 from a drug overdose in 1962 – is said to have paid $1,440 for the custom piece to the designer, and it holds the record for the for the most expensive dress sold at an auction, making it one of the most expensive dresses in the world. 

Legend has it that the garment was so tight, Marilyn had to be sewn into the dress prior to her performance for the President.

Kim had the same struggle when she discovered the dress didn’t fit her, and began to cry when she learned that the dress could not be altered. 

The ex-wife of Kanye West told Vogue how she went on a ruthlessly strict diet deadline in order to slim down and wear the dress to the Met. 

‘I would wear a sauna suit twice a day, run on the treadmill, completely cut out all sugar and all carbs, and just eat the cleanest veggies and protein,’ she told the outlet. ‘I didn’t starve myself, but I was so strict.’

Marilyn’s unique hourglass figure and exact measurements have been debated for decades, but one dress maker claimed she was 5’5″ tall, with a 35″ bust, 22″ waist, and 35″ hips. Her bra size was said to be 36D. 

Kim once said of her own measurements: ‘I am a size 27 jeans… My measurements are 38, 26, 39. But remember I am 5’2″ and 1/2 and everyone carries their weight in different places.’

Kim is said to have left her hotel on Monday covered up in a dressing gown, and had barricades set up outside of her hotel to make sure no one saw the outfit before her red carpet appearance.

When she got to the Met Gala, there was a secret dressing room set up for her near the steps where a conservationist from Ripley’s met her to help fit the dress, who was wearing special gloves.

Kim even said that she didn’t wear any body makeup, as she usually would do at such an event, in order to preserve the dress.
