Kimberley Garner Stuns in Black Bikini in St Tropez

showcased her incredible figure in a halterneck black bikini as she soaked up the sun in St Tropez. 

The former star, 35, took to Instagram on Tuesday to share her latest swimwear design from her brand, Sunday Swim. 

Kimberley showed off her cleavage and toned stomach in the plunging top and matching thong. 

Styling her blonde hair down, the former television personality proved she was the best advertisement for her brand as she posed in a series of shots by the pool at the five-star hotel Cheval Blanc and on the beach. 

Kimberley captioned the post: 'Quiet St Tropez very start of season. My new design I created of the little black bikini, classic old Hollywood high rise.

'I’m loving using thicker straps and a higher cut on the hips this season. What do you think? (Made in London always) my new summer bikini collection.'

Back in February, Kimberley revealed she was in a new relationship after she posted a video of her locked in a passionate kiss with a mystery man on a beach in the Maldives.

Kimberley, who previously dated trader William Claeyssens de Tena, didn't name her new partner, yet she was clearly smitten as he inspired her swimwear brand.

She told Eden Confidential at the time: 'I am in a new relationship but it's early days.

'We met through friends over the summer [last year] and we started dating three months ago.'

The swimwear designer said her boyfriend has already been making a positive change in her life and has inspired some of the menswear designs in her rebranded unisex label which is now called Sunday.

She added: 'It’s like a his-and-her concept. It’s a cute, fun thing to do. My boyfriend loves wearing the designs.'

Kimberley first launched her swimwear line in 2013, a year after she appeared on the third season of Made In Chelsea, and it has flourished over the years.

Despite now enjoying success as a swimwear designer, Kimberley previously revealed how she used to pretend to be an intern when she first started the business, because no one took her seriously.

However, the property heiress insisted she's more than just the face of her line and is involved with every aspect of creating her sell-out swimwear range.

She previously told the Daily Mail: 'I think people sometimes think that I’m only the face, but I am responsible for every bit of the business.

'I was 18 when I started my first company - I came up with an idea, stayed up for days learning how to register the company and teaching myself. It became very successful overnight.'

She explained: 'However, as I was only 18, no one ever imagined it was mine. I was a young blonde girl with a soft voice.

'No one would take me seriously or realise it was my company. So, I pretended to be the intern!

'I handled all the meetings, phone calls, and emails for the company. When it became a success, I put all the revenues into starting Kimberley London.'
