New York can see right through Kate Moss's fashion

Debuting her Topshop range in New York, the model, apparently braless, made a traffic-stopping appearance.

She turned heads while stepping out in Madison Avenue in a sheer see-through dress which put her knickers on show.

Despite looking a little underdressed, the model was in good spirits - she was out to toast the US launch of her line with an exclusive party at Barneys.

Inside, Moss totted a glass of champagne, briefly chatted with reporters and posed for photographers.

The media shy model modestly played down the hype surrounding her range, saying: "I don't know if it stands out. I know what I like."

Singer Amy Winehouse, Sadie Frost and Sir Philip Green were also on hand at the party to lend support.

Of her pal's fashion range, Frost said: "It's nice that it's got its own identity and is accessible."

Barneys will sell 26 pieces from Kate's collection at the Madison Avenue flagship store, among others.

Simon Doonan, Barneys creative director, raved about the range: "[It's] the first celebrity line with real fashion cred. A lot of others put their name on clothing labels, and it doesn't mean a hell of a whole lot."

"People are fascinated and intrigued by the way she puts herself together.

"There's an effortlessness to it and a savoir-faire that has made her a style icon. She slings those outfits together herself."

It's has already been a whirlwind stop for Moss, who lead the charge at the annual Costume Institute gala a night earlier.

While Moss' career goes from strength to strength, the same can not be said for her personal life.

During her absence from London, troubled boyfriend Pete Doherty again found himself in strife - he was arrested over the weekend on suspicion of possessing a class A drug.
