The 17-year-old is gearing up for her 18th birthday and what better way to do that than by wearing leather?

At one time it was just Kim Kardashian who caught our eye – these days all the Kardashian/Jenner girls manage to turn heads time and time again.

But Kylie Jenner – the youngest in the klan – is fast proving she is in fact the sister with the best and most interesting sense of style.

And last night she proved our point by wearing a skintight leather jumpsuit – which we can’t imagine any of her other sisters wearing, can you?

The 17-year-old, who turns 18 in just three days, rocked the outfit perfectly – completing it of course with sky high heels.

Her change of direction style wise may have something to do with reports that Kanye West has reportedly advised her to stop dressing like wife Kim.

The rapper is a big supporter of Kim’s half-sister and thinks she has great “potential” to become a superstar in her own right so he told her to “create her own identity” rather than copy Kim’s style.

A source told “Kanye is Kylie’s biggest supporter and loves the young lady she is becoming. He’s definitely been championing her for years as he sees real superstar potential in Kylie.

“That’s why he felt OK telling her that she needs to stop copying every move Kim makes and create her own identity.”

Kylie paid attention to her brother-in-law’s advice but admitted she can’t help but be inspired by Kim’s look because she respects her fashion sense so much.

The source added: “Kanye worships Kim and he has told Kylie there can only be one of her. Kylie hears what he’s saying but honestly, (she) doesn’t know where to take her look at this point. She’s digging her looks and style and doesn’t really care if she’s stepping on Kim’s toes a little.”
