It's one of the breed of bespoke tailors, not on Savile Row, but on the fringe. Boateng's made-to-measure suits are sought after (by rock luminaries George Michael, Mick Jagger, Bill Wyman, and even Lisa Stansfield) for their exclusive fabrics, fashionable detail, and shock-color lining as well as great classic cut. If custom tailoring is out of financial reach (upward of £2,000), there's a ready-to-wear collection, or the zappiest ties to be had in town (from £60). Tube: Piccadilly Circus.
