The photo prominently featured Kim’s svelte back as she crouched to the floor with her trim arms on display.

Her long, black hair was thrown over one of her shoulders and her underwear was visible as she sat in her black leather trousers.

She captioned the post ‘MISSING LA NIGHTS WITH YOU’ and tagged artist Mert Alas as the photographer.

The photo garnered plenty of flame emoji reactions from fans – as well as reaction from several who noticed just how trim she looked.

‘So skinny now!!,’ remarked one commenter.

‘Should have been titled I really just wanna show how skinny my back looks,’ another wrote.

Kim has clearly maintained the weight loss she achieved last year, after going on a diet to fit into Marilyn Monroe’s iconic dress for the Met Gala.

Shockingly, Kim managed to drop 16 pounds in just three weeks to fit into the dress Monroe wore while serenading Happy Birthday to President Kennedy in 1962.

She later admitted she had lost a few more pounds: ‘I’m down 21 pounds now. I’m not trying to lose any more weight, but I have more energy than ever,’ she said on the TODAY show in June 2022.

‘I cut out so much sugar. A lot of junk food I was eating. I didn’t realize it. A lot of fried foods. And I just completely changed my lifestyle,’ she added.

Kim was famed for her curvy figure, but has been shrinking this past year (pictured L in 2015 and R in 2023)

In order to do so, Kim revealed she wore a sauna suit twice a day, ran on the treadmill, eliminated all sugar and carbs from her diet, and consume ‘clean’ vegetables and protein.

Unsurprisingly, the Hulu star came under an immense amount of criticism for the diet, with many branding it ‘unhealthy’ – including actress Lily Reinhart, who said Kim’s ‘ignorance is other-worldly and disgusting’.

However, the star’s personal trainer, Don ‘DB’ Brooks, hit back at trolls and explained that it ‘wasn’t like starving yourself’, noting that she ‘put the work in’.

‘So I mean I was there through the process, so it wasn’t like a starving yourself type of thing. I mean she went on a real balanced diet and at times, you know, she wouldn’t eat as much. But then the second thing was she was in the gym and put the work in.’

In June 2022, Kim hit back at the criticism and insisted she ‘didn’t do anything unhealthy’ as she compared her diet to Christian Bale’s transformation for The Machinist.

Chatting to The New York Times, Kim shared that she lost the weight through diet, a sauna suit and running twice a day and explained: ‘I didn’t do anything unhealthy’.

Christian Bale famously lost almost five stone for his role in movie The Machinist, with Kim revealing she doesn’t see a difference with her own transformation.

‘OK, Christian Bale can do it for a movie role and that is acceptable,’ she quipped.

Referencing Renée Zellweger’s weight gain to play her eponymous role in the Bridget Jones’ Diary movie, Kim continued: ‘Even Renée Zellweger gained weight for a role. It’s all the same to me. I wasn’t saying, “Hey everyone, why don’t you go lose this weight in a short period of time?”‘

Showing just how much fitting into the dress meant to her, when asked what would have happened if she hadn’t reached her weight goal, she replied: ‘I just simply couldn’t have gone, which wouldn’t have mattered, It was just important to me to reach that goal.’

Laser away: In addition to working out, Kim also credited a laser procedure for helping to ‘tighten’ her stomach

Beauty is pain: She shared a shot of the procedure to her account back in August 2022, calling it a ‘game changer’ though admitting it was ‘painful’

The Marilyn dress was bought at auction by Ripley’s Believe It or Not museum chain, with no adjustments allowed to be made to the original gown.

In addition to working out, Kim also credited a laser procedure for helping to ‘tighten’ her stomach.

She shared a shot of the procedure to her account back in August 2022, calling it a ‘game changer’ though admitting it was ‘painful.’

‘This is a game changer!!! I did Morpheus laser to tighten my stomach at @DrGhavami’s spa,’ she wrote, adding, ‘I think this is my fave laser but it’s painful lol but worth it!’

Kim previously boasted about her shapeshifting powers on the Hulu series The Kardashians, where she recounted being able to fit into just about anything as she prepared to try on a replica of the Marilyn dress.

‘The width of my shoulders and my body makes me like a shapeshifter. I can squeeze into anything. But no one trusted us for years, they would never send samples.

‘And then once I would get to Paris and try on the samples, they would be like, “Oh wait she actually fits in our stuff.” So I don’t know how to convince the guy that owns the original Marilyn dress that I’m a shapeshifter.’
