If summer had an official fabric, it would be seersucker. With its superior breathability and everlasting status as the go-to preppy staple, it has secured its place as the default warm weather fabric. United Bamboo, the New York-based label founded by Japanese transplants, knows when not to mess with a good thing, and has designed a classic blazer with enough flourish to please even the most discerning customer. With a double-lined lapel reminiscent of a tennis sweater, this two button jacket has enough class to transition from the daytime courts into the evening socials. Pair it with matching pants for a more formal look, or wear it alone for just a hint of your country club roots. For information on where to buy, see Gargyle.com.
