There’s been a long history of streetwear brands having a bit of fun at the expense of established luxury fashion brands (contravening the notion that imitation is the sincerest form of flattery), but a simple T-shirt from Brooklyn’s What About Yves has resulted in the dissolution of a longstanding business relationship between a retailer and one of those aforementioned luxury labels. Yesterday, Sarah Andelman, the creative director and a part owner of colette, reported that Saint Laurent was severing ties with her influential Paris store — a partnership that dated back to 1998. Furthermore, Andelman was not invited to view the Spring 2014 Saint Laurent collection by designer Hedi Slimane, and colette’s orders from that collection — totaling $285,738 at current exchange rates — were summarily canceled. All because the store had sold about 300 of the What About Yves’ “Ain’t Laurent Without Yves” tee. The winner here has to be What About Yves, who gets a good amount of free press and notoriety, both of which are always at a premium in the fashion world.
