Kim Kardashian certainly knows how to make an entrance and she did just that last night as she launched her Kardashian Kollection with sister Kourtney in London.

Kim left it fans on Twitter to choose her outfit for the launch of the range Kollection and we have to say - they've got pretty good taste.

The tiny, sparkly LBD that Kim wore to the party thrown by retail mogul Philip Green is just one of the pieces that will be available in 200 Dorothy Perkins stores around the country.

But despite having her own fashion line, Kim admits that she still makes the odd fashion faux pas.

Speaking at the launch party, she told the Evening Standard: "I look back at things from really recently and I'm like, 'Oh my God, why did I wear that, what was I thinking?'

"But it's fun. You see what you like and what you don't and experiment."

Joining Kim in London was her boyfriend Kanye West, who jetted in to support the reality star with her latest venture.

The pair were spotted squeezing in a quick bite together at posh eaterie Hakkasan earlier in the day.

And it wouldn't be a showbiz bash without a smattering of 'X Factor' stars would it?

Jahmene Douglas, Rylan Clark, James Arthur, District 3 and Ella Henderson all rocked up hoping to catch a glimpse of Kim and Kourtney but it was Ella who seemed the most excited at the prospect.
