With a big store in Central already, why would upscale fashion house YSL want to open a tiny pop-up store on the edge of NoHo? Because it's the fashionable thing. With an artsy cocktail party on Friday night, the French brand opened its temporary storefront at Kau U Fong's Madhouse Contemporary Gallery to house its first unisex collection. Apparently this is something Yves Saint Laurent designer Stefano Pilati has also done in Milan, Paris, London and Tokyo. Naturally the label's Asia boss, Mimi Tang (right), had to make sure we joined the exclusive list. 'The company wants to do something that stimulates more ideas,' Tang said. 'The pop-up boutique started in New York this year. We hope our customers can enjoy the intellectual designs in this economic downturn. We want the collection to have an artistic connection, where the customer can see his or her true self through wearing our clothes. 'We chose this gallery for its location and unique feel. We didn't want a really big place. The collection is about intimacy with oneself.' In addition to the gender-bending apparel, four local photographers were recruited to present pictures of androgyny. To ensure word about the temporary shop got out, YSL even tried guerilla marketing with four motorcyclists in special YSL jumpsuits riding around Central all weekend. No doubt some people assumed they were just escapees from the Sevens. The YSL Pop-up shop is open until Friday.
