If J. Crew isn't preppy enough for you, try Hackett, with branches in Covent Garden, Spitalfields, St. James's, Soho, Mayfair, and The City. Originally a posh thrift shop recycling cricket flannels, hunting pinks, Oxford brogues, and other staples of a British gentleman's wardrobe, Hackett now creates its own line and has become a genuine—and very good—men's outfitter. The look is traditional and classic, with best buys including polo shirts, corduroys, and striped scarves. There's also a boys' line for the junior man-about-town.
