     New York has taken the title of the world's top fashion capital from Milan. The annual survey suggest

that the top five fashion cities are facing competition from Asia and Australia. New York had been the top fashion city for five years, but Milan took the title in 2009. The survey was made by the Global Language Monitor, a US based organization. It tracks the frequency(频率) of words and phrases in the media, on

the Internet and throughout the blog. With the US economy recovering, New York once again took the

top title. Hong Kong took second place. It was followed by London, Paris and Los Angeles. The other

top 10 cities were Milan, Sydney, Miami, Barcelona and Madrid.

    "Because of the new economic situation, the global fashion centers have also changed a lot, "said Bekka Payack. the Manhattan-based fashion reporter for the Global Language Monitor. "The new list shows that global fashion centers will change now and then. Compared with the traditional fashion cities, some new ones are performing better and better. "She said that perhaps this is new trend, and it is the first sign that the

traditional top five fashion cities--New York, Paris, London, Milan, and Rome--do not control global

fashion any more.

    The biggest changes in the list are Hong Kong, Madrid and Melbourne. The Group said that the top

newcomers to the list include Amsterdam at number 17, Cape Town at 23, Johannesburg at 25 and

Vienna at 27.
