Dan and Dean Caten, the twins behind Dsquared2, see eye to eye

True to form, Dan and Dean Caten start their interview with the clink of champagne glasses. The Canadian identical twins behind the exuberant DSquared2 label aren't toasting anything in particular, as Dan, the younger of the two by mere minutes, concedes.

The Caten brothers, 49, are making a whistle-stop tour of Hong Kong and Shanghai, "christening", as they say, two recently opened Dsquared2 boutiques in Hong Kong's IFC and Shanghai's IAPM malls.

As if that didn't give them enough to do, they are also fielding questions from interviewers, hosting cocktail parties and attending private dinners. In Hong Kong, there was even the extravagance of a lavish pool party at the Grand Hyatt, themed around their jungle-inspired spring-summer menswear collection.

"It's an indelible part of the DNA," says Dan, remarking on the theatricality of the pool party. "We always do something dramatic, especially with Joyce. We've done two fashion shows here. This time we wanted to do something around the theme of the collection, a tropicana, tiki kind of thing.

"We thought it would be funny to do it outside," adds Dan, looking out of the window and considering the humidity. "I mean, it's not that hot," he says, in a reference to those who had tried to talk him out of the idea.

DSquared2 has become a byword for flamboyant clothes, and has gained attention through its outrageous runway shows, which are now a must-see during Milan fashion week.
