There's no mistaking Steven Alan for a conceptual designer. He makes commodity clothes, plain and simple. This season, though, he did tease a bit of concept : he was thinking about space, and about the uniforms people wear in space, and movies made about space travel, and so on. And so even though his latest menswear collection was chockablock with staple pieces like the perfect pair of glossy twill black shorts, it also digressed into a few unexpected but appealing longueurs. Consider, for instance, Steven Alan's mock-neck tee in white, redolent of the stuff worn by the astronauts in "2001: A apace odyssey", or his short-sleeve button-downs, with their signature trim Steven Alan silhouette, executed in fabrics such as a cartoon Martian head microprint. There was wit here. The emphasis, though, was on his elevated basics -sometimes given a twist, in the case of a cropped-collar polo, or a tee-shirt in cotton twill, and sometimes just finessed and re-finessed, as with his soft-shouldered but not unstructured blazer, or his pieces in Japanese chambray and denim, or the super stripped-down bombers and anoraks. Not rocket science, this, but clothes your average rocket scientists -or your average cosmonaut, for that matter- would be delighted to wear.
