Kim! Now Kylie Jenner, 18, jumps on the waist training trend loved by her big sisters

Kim Kardashian may have single-handedly ignited the waist training trend, with her sisters Khloe and Kourtney quickly getting in on the action.

And now even the youngest of the siblings - 18-year-old Kylie Jenner - has revealed she is a fan, promoting a waist trainer on her Instagram on Saturday.

Kylie shared a selfie from her $2.7million Calabasas mansion, revealing that she had just been for a stroll in the corseted device.

Just took my dogs on a walk wearing only da best @premadonna87 @waistgangsociety,' she wrote alongside the snap.

'Nothing wrong with a little extra help. They also got some new stuff in I wanna try.'

Kylie wore the waist trainer over a black tank top and black and white printed leggings. She styled her dark locks in a top knot and sported just a little make-up.

Jessica Alba, Amber Rose and Kim Zolciak are also fans of wearing corsets to try and mould their figures into an hourglass shape.

Despite the recent popularity of waist trainers, doctors have said that they can compress your internal organs and cause issues.

Kylie certainly doesn't need a waist trainer, but she is a fan of following in the footsteps of Kim - particularly when it comes to trends and outfits

Later on Saturday, she revealed on Instagram that she had 'stolen' the 35-year-old's make-up artist Mario for the afternoon.

Kylie posted a selfie while wearing huge false eyelashes, gold glittering eyeshadow, lashings of bronzer and pink lipstick. She was sporting just a fluffy white bathrobe.

The previous evening, the teen attended Balmain creative director Olivier Rousteing's birthday party alongside Kim, Kourtney, and mom Kris Jenner.

Kylie was also joined by her 25-year-old rapper boyfriend Tyga, while her rumoured ex Jaden Smith was there too.
