The ‘Elbows In The Air’ is the new Instagram pose bikini babes Ferne McCann, Holly Hagan and Leigh-Anne Pinnock love – just make sure you shave your pits

SUMMER is officially underway, and with our tans and bikinis at the ready, it's absolutely key to be familiar with the hottest pose for those all important Instagram snaps.

And this year it couldn't be easier - as stars like Ferne McCann and Leigh-Anne Pinnock have proven - because all you need to ace the new trend is to lift your arms up.

One of the simplest Instagram trends to date, the 'Elbows In The Air' involves lifting up your arms while keeping your elbows bent.

And not only does it make pictures appear candid, with celebs looking like they're stretching after a dip in the pool - it also has a slimming effect as your stretch up towards the sky.

Elongating your body ensures perfect posture too, instantly trimming down the figure and enhancing your bikini body - just ensure you've shaved your pits for this one.

While hitting up the beach in Marbella, 29-year-old Ferne nailed the trend, showing off the best of her beach-ready figure.

In June, the mum-of-one started off the trend while holidaying with her daughter Sunday, 1, proudly lifting her elbows high as she sunbathed poolside.

And she's not the only celeb who's been trying it out for size, and with success shown by the hundreds of thousands of likes it's raked in on Instagram.

Little Mix singer Leigh-Anne Pinnock showed her best attempt at the post while holidaying in Barcelona this week as part of a girl's getaway.

Preparing for the Little Mix world tour later this year, Leigh-Anne took to the social media site in a mint green bikini and posed as pretending to fix her hair.

Just weeks before she was spotted practising the pose on the rocks of Mykonos island - where the star holidayed with boyfriend and football player Andre Grey.

Meanwhile, model Lottie Moss, who knows a thing or two about striking a pose, proved the 'Elbows In The Air' is suitable for the runway as she also posed in the Spanish city, Barcelona.

And another high-fashion heroine Bella Hadid, who stopped for a snap in Mykonos, as well as famous model Demi Rose, also on the Greek island, proved it to be popular.

Even Kourtney Kardashian, who went far afield to Costa Rica to get that perfect snap has been trying it - while Geordie Shore's Sophie Kasaei showed off the stomach-tightening appearance of the look.
