Zest up your swimwear in Kourtney's Triangl bikini

The beloved Australian brand that made their name in punchy colorblock swimsuits has moved onto greener pastures. Or at least..modernized with the current trends.

That being said the label has mostly done away with their two-toned suits and designed a new collection that is monochromatic, simple and chic.

Of course, sticking to their trademark use of neoprene fabrics, these Triangl suits are universally flattering with a sporty flair.

Kourtney has decided to get a piece of the action in this zesty colored bralette number with sexy high-cut briefs. The two-piece is sexy and supportive and sure to turn heads.

'Swipe up to see the one move I never skip during a workout' the mother-of-three wrote on the sizzling image.

It's not clear where the photo was taken and whether it was a throwback, but in it Kourtney gives serious vacation vibes in the neon two-piece with her dark tresses tied up in a ponytail.

The sexy display came after her ex-boyfriend Scott, 34, told Kourtney's sister Kim Kardashian that he fears his days in the Kardashian fold are numbered.

In a new teaser for Keeping Up With The Kardashians Scott admitted he feels 'insecure' and 'scared' that Kourtney's new beau - 24-year-old model Younes Bendjima - will replace him.

'What if there is a new Scott and everyone thinks, "We don't really need to be close to him any more." 

'It's a scary thing for me.'

Scott said: 'Like, if Kourtney met someone, fell in love and got married and then everyone’s like, "Eh, we have a new Scott — we don’t really need to be close with him anymore."'

But the chances Scott will be totally cut off are not likely as he and Kourtney share three kids — Mason, aged seven, Penelope, aged five, and Reign, aged two.

They split in 2015 after nine years together. 

He added: 'Even though I get it — we have kids [together]. But it’s a scary thing for me.'

Kim responded: 'My true advice would be let’s cross that bridge when we get to it.'

In her confessional to E! cameras, Kim said, 'It’s taking him a little big longer — or a lot longer — than Kourtney.'

At the time Scott was being pictured with numerous young models as he gallivanted around Europe in May.

But the playboy has now fallen for 19-year-old Sofia Richie, going public with their relationship in September.
