It seems like it’s all about designer collaborations these days. Adidas and Diesel, Stella and Notify, everybody and H&M. Now Ben Sherman is jumping on the bandwagon, partnering with design and record label PPQ for a diffusion line. Though PPQ isn't so known in America, they're like an upscale Heatherette in London - this October, they opened their fashion show with Peaches Geldof and Agyness Deyn (in that order), and the MisShapes played their after party. The limited-edition collection launches this March with only five dresses, all meant to capsule decades of musical style. The outfits begin with a Mod-inspired shift for the 60’s and end with a high-necked lace frock, which references (they say) the Cranberries, KT Tunstall and other moody songstresses from today. Ben Sherman is only making 175 of the dresses, and only 25 for the US market. We think this is a cute idea, but something else is bugging us: If the Indie Dress at left comes in white, it’s going to look a lot like the Chiffon with Velvet Dress from Erin Featherston’s diffusion line. But the Ben Sherman version is £180 - can we still rock out to the Kills if we shop at Target?
