What's her trick? Kylie Jenner's 27-inch waist looks impossibly tiny as she wears skintight dress while sitting on a bed

Kylie Jenner's body keeps changing with time.

And on Saturday the 19-year-old Keeping Up With The Kardashians star looked different yet again.

In a quick Snapchat clip, the Elle model appeared to have a very tiny waistline as she sat on a bed with Tyga, her boyfriend of nearly two years, sitting behind her.

It looked as if her waist was cinched by a black belt.

It may have just been how the Lip Kit founder was sitting but her waist appeared very small in comparison with her hips and thighs.

Strut your stuff in Kylie's Yeezy boots

Kylie Jenner took a break from her busy NYFW schedule to enjoy a romantic dinner date with her beau Tyga of Friday.

We're pretty sure Kylie would have shown off some sort of skimpy ensemble when she went into the restaurant but she kept her self protected against the elements in an oversized fur coat teamed with a pair of long suede boots whilst outside.

Over the knee boots have saturated the market with designers and the high street alike producing their own variations, so this beige suede pair cut just below the knee are a fresh take on the look.

It's no surprise these boots are from Kylie's brother-in-law's label, Yeezy. And the good news is if you're loving them they're still available to buy online now at MyTheresa!

The E! teen has been vocal about not changing her body with the help of cosmetic procedures.

She has insisted she has not had butt injections or breast implants, but she has coped to getting lip fillers. The star only two years ago was extremely slender like sister Kendall. Not she has curves like Kim Kardashian, 36.

The same day she posted the clip, Kylie also shared images from her new Kylie Jenner pop-up shop in NYC.

Her pop-up shop in LA's Topanga neighborhood was a smashing success.

Also on Saturday Kendall modeled clothing from her new line with Kylie. She had on a black sheer top that showed off her chest.
