Each week through June 4, the top-notch men's e-tailer Mr Porter will unveil an exclusive capsule collection, drawing both from cult labels and established designers like Raf Simons. The first one, on sale May 14, comes from the Tokyo brand Beams Plus, and fuses two classic American looks that the Japanese have long fetishized - surf and Ivy League style - with comic results: khaki board shorts, anyone? Forthcoming collections include Alexander Wang's sophisticated update of jock staples (like collared baseball tees) and elegant sportswear from Ami inspired by the "bobos" who hang around the Canal Saint-Martin in Paris.
