It wouldn’t hold up to a brisk morning swim.

But Kim Kardashian’s knit ʙικιɴι was the perfect option for a posing session, highlighting her shapely rear as she snapped pictures of the Mexican sunset.

Seemingly cut from a similar material to the Cosy Knit range of her shapewear brand Skims, the two-piece featured a halterneck tie at the neck, and high-cut cheek flaunting rear.

If Kim were to launch her own swimwear range, a seemingly natural next step for the fashion-minded businesswoman, she wouldn’t need to shell out on models – with her famous curves the perfect vehicle for advertising her wares.

The reality star was pictured as she relaxed on the beach in Cabo, where she is staying at the luxury Esperanza H๏τel and Resort, which offers an ocean front villa for around $7,000 a night.

For her trip she wore her hair off her face in a long braid, and kept her eyes protected with a tiny pair of stylish sunglᴀsses.

The outfit is sure to join the ranks of Kim’s ‘archived’ clothing, after the Keeping Up With The Kardashians star admitted she keeps every single outfit she wears.

The 39-year-old star attaches a picture of when she wore it with each item.

When one fan tweeted, ‘One important question that needs answers is, do you keep any of these coats in your archive @KimKardashian? They’re all gold!’, Kim replied: ‘I have every single coat and each one of these outfits all archived with the pH๏τo attached to each look! Don’t worry!’

Meanwhile, Kim previously revealed she has a ‘temperature controlled’ storage facility for every outfit she has worn that is linked to an app on her phone.
