10 years older: Kylie Jenner looked much older than her 14 years last night as she attended the launch of the Kardashian Khaos store in Las Vegas wearing a Hervé Léger bandage dress

For the modern celebrity, a Hervé Léger bandage dress is something of a wardrobe staple, but it's not often you see a teenager clad in one of the famous dresses.

However, last night 14-year-old Kylie Jenner decided to ignore her tender age and go all out in a silver sequinned number for the launch of Kardashian Khaos in Las Vegas.

The pretty brunette teamed the sophisticated dress with a pair of vertiginous Christian Louboutin heels, similar to the styles previously sported by her older sisters.

Meeting and greeting: Teenager Kylie looked more than confident as she arrived for the opening of the store at the Mirage Casino

Kylie, who is dating teen singer Cody Simpson, left her long hair loose around her shoulders, and wore minimal make-up as she posed for photographers at the event.

While Kylie's older sister Kendall, 16, has come under fire in the past for dressing older than her years, it's the first time Kylie, the youngest of the Kardashian/Jenner clan, has faced such criticism.

But the girls are soon to face the same level of fame as their older sisters, Kim, Kourtney and Khloe, after it was announced the duo will soon be getting their own reality show.

The head of the cable channel E! has revealed she plans to add more Kardashians to the roster of TV shows featuring the family.

Bonnie Hammer said the network is looking at making shows featuring mum Kris Jenner's two daughters with husband Bruce.

She said of the series: 'I think it will have its own life expectancy and we'll just go along with it and help hone what's right for E! and what's not right for E! as we develop a whole other world.'

Both Kendall and Kylie are beginning to establish themselves as models, with Kendall slightly ahead of her younger sibling after landing covers of magazines including the recent Lovecat and Teen Prom publication.

In a recent interview, Kendall told Teen Prom that she used to be nervous when she first began to appear on her family's reality TV shows but that she and her sister now consider it 'normal'.

She said: 'I used to be really shy around the cameras when we started filming. But I think Kylie and I are both used to it now. It’s normal for us.'

A website post by Kim today revealed her excitement at the shop, the latest in a number of stores the sisters have opened across the globe.

'When I was young, my dad would pile all the kids into the car and take us to The Mirage in Las Vegas to see the white tigers!' she wrote.

I never in my life dreamed that one day my sisters, my mom and I would have our first ‘celebrity lifestyle’ boutique there!

Happy and relaxed: Kourtney and Khloe seemed thrilled to be attending the launch of the shop, which will sell 'one of a kind' items

'Last week our Kardashian Khaos store opened! We’ve had an amazing response and customers from all over the world are coming to buy our made to order, one-of-a-kind, exclusive Kardashian souvenir products!' she added.

'I can’t wait for you all to come and see it. I think you’ll love it!' she continued, posting up several pictures of the store on her page.
