A question for the ladies: how far can you walk in heels? Models tend to make it look easy, but can they sustain their poise over three whole kilometres?

The World's Greatest Catwalk 2012, which is being staged in Tsim Sha Tsui today, is not in fact an Olympic event, but its organisers do hope to smash the record for the world's longest fashion runway.

Running the length of the Avenue of Stars, from the Hong Kong Museum of Art, and onto Hong Chong Road in east Tsim Sha Tsui, a carpet of striking pink is being rolled out along 1.6 kilometres, resulting in a round trip of more than three kilometres. The current world record of 2.812 kilometres was set in Sydney in August.

The event, which is being staged by the Hong Kong Fashion Designers Association in collaboration with the Danish Fashion Institute (which hosted a World's Greatest Catwalk show in Copenhagen, in 2010), is part of Hong Kong Design Year and features more than 300 looks and models - women and men, from here and there.

"It's a celebration of the fashion of Hong Kong and Denmark," says project director Bonita Cheung, who confirms only the women will be turned out in heels. "It also serves as a valuable design and cultural exchange and will reinforce the status of two influential fashion capitals in Asia and Europe."

Designers presenting include Camilla Salgaard, Henrik Vibskov, Hidy Ng and a legion of emerging local talents.

"Denmark is a quasi-socialist country which has bad weather and lots of tall blondes, so there are many similarities between it and Hong Kong," a spokesperson added.

Actually, we made that bit up.

Proceedings get under way on the Tsim Sha Tsui promenade at 2pm.

Let's hope it doesn't rain.
