Thirty-one-year-old British designer Matthew Miller has been busy of late. Fresh off a Fall/Winter 2013 showing in London — his fifth — Miller was one of four London menswear designers invited to collaborate with MR PORTER on an exclusive capsule collection. The offerings consist of three pieces from each label — Katie Eary, Richard Nicoll and Sibling were the others commissioned — with a cotton-jersey sweatshirt, piqué polo shirt and cotton-jersey tee being Miller’s contributions to the group. In a primary color palette of black, each pared-down piece showcases the structured tailoring that Miller has made his signature while also offering new elements of function and interaction. The foil sheet pockets on all three garments are initially sealed but can be torn off, and along with red leather pull tabs, provide each piece with a unique, visual flair. Available now, the Matthew Miller for MR PORTER 2013 Capsule Collection may be purchased online.
