Long before street fashion started wafting upward like tendrils of heat from summer concrete, the nautical workwear of fishermen bubbled up from the murky waters of Brittany into the haute world of Coco Chanel. Jean-Paul Sartre's coterie brought the tee to the streets of St. Germain, and Lee Marvin is credited as the first actor to brandish the stripe in a Hollywood movie. He did so in 1953's The Wild One, and his stripes gave him an even harder edge than co-star Marlon Brando's famed white tee rolled up with a pack of cigarettes. Barbour serves up their Atlantis Heritage T-shirt in two classic color schemes (white-on-navy and navy-on-white), and, as is more common on Breton-striped sweaters, lines the left shoulder with three buttons. Stylish but conventional, the Breton t-shirt is for outsiders as well as tongue-in-cheek insiders. And it always looks good near a body of water. Here are five examples to aspire to, from left to right: Andy Warhol, Pablo Picasso, Lee Marvin, James Dean, Cary Grant.

When leather goods designers Moore & Giles set out to produce a leather conditioner, they contacted Virginia-based saddle manufacturer Tad Coffin. Coffin grew up on Long Island, and started riding horses at age 10. To say he had a knack for it is an understatement.He finished off his amateur horse-riding career with back-to-back double gold medal wins. At both the 1975 Pan American Games in Mexico and the 1976 Olympic Games in Montreal, he competed and won both the solo and team "eventing" events (pardon the redundancy). Eventing is the triathlon of equestrian events, comprised of dressage, cross-country, and show jumping. It requires a great deal of trust and respect between the horse--in this case, Bally Cor--and the rider. And the only other thing between the horse and rider, of course, is the saddle. A dried out, unconditioned saddle can be the difference between your horse "refusing" to jump the obstacles and two gold medals swinging around your neck. So if you want your leather--Moore & Giles, saddle, or otherwise--to live a long and respectable life, you'll need to condition it every now and again.

Yesterday we showed you how a sophisticated gent like Mad Men's Pete Campbell does madras. Today we show you how Bill Murray does it. On the red carpet for the Cannes premiere of Wes Anderson's Moonlight Kingdom, the comedian modeled a motley madras blazer--and he kept the look going with his shirt and, yes, pants. Can there be such a thing as too much madras? You decide. More pictures of Murray, as well as a dapper Wes Anderson and costars Bruce Willis, Ed Norton, and Tilda Swinton over at Buzzfeed.

Any menswear fan that watched the season premiere of Mad Men probably paid more attention to Pete when he appeared at Don Draper's birthday party in a plaid, madras sportcoat. This Spring, Bills' Khakis broke out a retro plaid for a loud Kentucky Derby/Memorial Day BBQ/Summer in the Hamptons/GTH sport coat. The coat is a featherweight at 3.4 ounces. Two buttons in what they're calling a "coral retro plaid". Sure to turn heads at any spring/summer event. Bills Khakis Coral Retro Plaid Sport Coat   $595
