“Sail off into the sunset in the most fashionable cotton of the spring” – available tomorrow, May 1, at 9 AM PT / 12 PM ET. The SKIMS description said, “@KimKardashian is wearing the Cotton Rib Low Back Onesie, size XS, in Stone.”

Some fans stated in the comments section that Kim could not possibly be an XS.

‘Kim is stunning but she’s not an XS,’ wrote Billienovena.”Could you just stop putting Kim Kardashian’s size on there or actually give the real size?” Chevygirlss continued. I’m not sure if people are genuinely falling for it. She isn’t very little.

Kim Kardashian looked ready to join the cast of Yellowstone as the show finishes shooting its fifth and final season. The 43-year-old reality TV diva was seen in a cowgirl hat and boots while posing on a vintage car at a California ranch

The beauty was modeling her latest nude-toned lingerie for her blockbuster brand SKIMS as she used the lush rolling hills as a backdrop

Some followers did not think SKIMS was being honest about the size Kim – who is 5ft2in – wears

And laila.touti insisted: ‘@skims you guys not accurate in sizes… im M i purchased M felt like xxs then i exchanged it to XL still feels like XS… the bodysuit is WAY too small.’

Then Jeannesque declared: ‘Enough of this bs – @kimkardashian is NOT an XS… and especially not in this onesie!’

The day before she had on a quaint floral print bra and undies as she added brown cowboy boots for a Cowgirl Cool look.

The mother-of-four posed in a farm setting as she held on to the door of a vintage mustard yellow car with a wood fence.

‘COMING MAY 1: NEW COTTON. The Cotton that started it all has a fresh, new look for spring! Shop new and signature styles in a limited edition palette Wednesday at 9AM PT / 12PM ET,’ the caption read from the blockbuster brand.

‘@KimKardashian wears the Cotton Rib Plunge Bralette, size S, and Boxer, size XS, in Marigold Rosebud Print.’

We already knew Kim was an XS in bikinis because her brand revealed that over a week ago.

But now they also shared that her bra size is a small which seems much smaller than one would expect as the 5ft2in goddess is always so busty on the red carpet.

‘Drive off into the sunset in spring’s 𝑠e𝑥iest Cotton – coming tomorrow, May 1 at 9AM PT / 12PM ET. @KimKardashian wears the Cotton Rib Low Back Onesie, size XS, in Stone,’ the SKIMS caption read

In the comments section some followers felt that there was no way Kim could be an XS. Billienovena wrote, ‘Kim is beautiful but she’s not an XS’

Chevygirlss added, ‘Can you either just stop putting Kim Kardashian’s size on there or actually give the real size.. I don’t know if anybody’s actually falling for it. She’s not an extra small.’ Then Jeannesque declared: ‘Enough of this bs – @kimkardashian is NOT an XS… and especially not in this onesie!’

She may be a XS in a bikini top and a S in a bra because she wears her bikini tops on the smaller side so it looks like she is busting out of it.

With a bra, she appears to want more coverage.

A size small usually means your bust is 33 inches, your waist is 26 inches and your hips are 35 inches.

In the past, Kim has not talked much about her size or weight too much, though she is thought to be 116lbs with a 24in waistline.

The fashion designer looked like she was about to bust out of the triangle bra.

The looker also showed off her abs and toned legs in the country western shoot.

The American Horror Story actress was wearing her dark hair down and wet as she had on red lipstick.

But the main focus was on her knockout and very toned figure as she showed off her abs, tiny waistline, sculpted legs and muscular arms while making the most of her bathing suits.

The ex of Pete Davidson gave her best Victoria’s Secret poses to help hawk the intimates collection.

Kardashian looked white hot in new SKIMS images released on Monday. The 42-year-old ex-wife of Kanye West had on a white bra and matching shorts with a quaint floral print as she added brown cowboy boots for a Cowgirl Cool look

The Hidden Hills, California resident got a like from Jenna Dewan.

The reality TV icon is currently starring on Hulu’s The Kardashians with mom Kris Jenner and siblings Kourtney, Khloe, Kendall and Kylie.

SKIMS is an American shapewear and clothing brand co-founded by Kim, Emma Grede and Jens Grede in June 2019.

Skims has a focus on body positivity and inclusivity across the brand and practice inclusive sizing. The company was valued at over $3.2 billion in January 2022.

This campaign is being released after Kardashian and Odell Beckham Jr have split up.

She may be a XS in a bikini top and a S in a bra because she wears her bikini tops on the smaller side so it looks like she is busting out of it. With a bra, she appears to want more coverage

The reality TV star and the American Football player enjoyed a six-month romance but are said to have now called time on the relationship.

A source told MailOnline: ‘They’re not seeing each other anymore right now.’

The split will come as a surprise as Odell, 31, who is currently a free agent, was reportedly set on a move to the Kansas City Chiefs in order to be closer to Kim, who is based in Los Angeles.

A source previously told DailyMail.com: ‘Odell is a free agent and is looking to sign with a team that will get him closer to LA to be closer to Kim.
