Kate Moss has helped launch the first US branch of British high street chain Topshop

The supermodel – who designs her own range of clothes for the franchise - joined the chain’s owner Sir Philip Green as the New York store was unveiled to the waiting crowd yesterday (02.04.09).

Kate looked stunning in a $250 floor-length green gown and fitted leather jacket from her new collection.

Despite the global economic downturn, Green is confident the US store - in New York’s SoHo district - can be as successful as it in Britain.

He said: "Where are the people walking around nude? People are still wearing clothes. They want to be inspired. They still want to shop. Get real."

The reasonably-priced New York branch will sell jeans for $40, T-shirts for $20 and $24 micro-shorts.

The launch was attended by host of celebrities including Jennifer Lopez, Jennifer Hudson and Vogue editor Anna Wintour.

Topshop’s arrival in New York – which was delayed by six months – has been built up around the city and cost up to $24 million.

The four-storey shop has 200 staff, 32 changing rooms and a DJ booth suspended from the ceiling.

If successful, Green anticipates opening up to 15 US stores, including ones on Miami, Las Vegas, Boston and Los Angeles.
