With millions of followers watching their every post, ensuring they look perfect in their Instagram snaps is now part and parcel of being a celebrity.

So it's little wonder mere mortals look to the stars' feeds and follow their lead in order to look their best - sparking trends including the 'Bambi' pose, which sees women perch on their knees with their legs tucked beneath them to flattering effect, and the 'migraine' pose - touching the temples in head shots for a lifting effect on the face.

Now we can expect to see social media adopting yet another trick for the camera; the Barbie foot.

According to Who What Wear, Instagram's hottest stars are all using an exaggerated pointed toe - as seen on Barbie - to elongate their legs.

And everyone from Kendall Jenner to Bella Hadid and Rosie Huntington-Whiteley is at it.

The website claims that pointing the feet - almost as though you're wearing a pair of invisible heels - gives the illusion of longer legs.

This is because high heels have a leg lengthening effect, and the pose gives the benefit of wearing shoes without ever having to put a pair on.

The name comes from the doll's feet, which are permanently arched so children can easily slip on her heels.

Celebrities have been using the technique most often in their bikini shots to make their bare legs seem leaner.

They pull the pose while sitting down and pointing their toes towards the ground.

It can also be done standing up, with its fans sticking one pointed foot in front of the other for maximum leg-lengthening effect.

The look can be achieved by balancing on the balls of the feet, and most will throw their hands behind their heads to show off more of their figures.

The biggest fans of the technique are the Kardashian-Jenner clan, who often use it in their risque Instagram snaps.

Model Bella Hadid has also made the most of her ultra long legs and pulled the pose in several of her sizzing shots.

Last summer the most popular pose was the Bambi, which saw the poser perched gingerly atop their own heels, sat with their legs folded directly underneath them.

The pose seemed to accentuate backsides and hips while making the waist appear narrower, which made it a sudden go-to for stars and models already hitting the sand and sea.

Called 'the Bambi pose' because of its similarity to the way a deer might sit with its legs folded underneath, the position was clearly meant to play up femininity.
