Psy, the rapper of ‘Gangnam Style’ hit song is in studio doing his next song.

Among other things, Psy’s sense of style helped to boost sales for most retailers in Japan. Ranging from the tortoiseshell sunglasses to the two-toned Oxfords, Psy’s Gangnam Style hit the waves with its dance style.

Psy’s stylist said only that the 35-year-old will be in a suit for the new song, whose title also remains a secret. The song will be released at an April 13 concert. “The basic concept for his upcoming song is again a formal suit but with a humourous twist. I plan to add an unexpected twist of fun,” Hong Hye-won said. “I made a point with a bow tie back in the Gangnam look. There is something like that for the new song.”

French eyewear designer Thierry Lasry has been besieged with questions about the two kinds of shades – the tortoiseshell, and black with gold temples, both called “The Variety”. “We have had a lot of requests from our customers who saw and loved his music video,” said Clara Mercier, marketing manager for Thierry Lasry, who said the tortoiseshell version was a limited edition. The black ones go for 335 euros ($NZ530).

“We obviously could have sold thousands had it not been a limited edition,” Mercier added.

Gabor, a German-based shoe maker, also benefited. Psy’s footwear was Christian Louboutin, but similar enough to one of Gabor’s styles. “Before Psy, Oxfords were not exactly popular,” said Lee Hyung-joo, Gabor marketing manager. “But now everyone, man or woman, old or young, fashionable or not, wants to try the Oxfords Psy wears.”
