I’m in Paris for the first time, and I was given one piece of advice to help me fit in: Don’t wear shorts. Europeans don’t, which means doing so is a surefire way to be pegged as a tourist. This is generally but not entirely true. The crowds at the French Open, in Roland Garros, do wear pants more often than shorts, even though it's been hot, and they are generally the most stylish tennis crowd I’ve yet seen. VIPs at the U.S. Open dress gaudier than those occupying box seats in Paris, but they're balanced out by the distressingly large number of fans who arrive in full tennis gear — headbands, wristbands, Nike shoes — as if they fear unpreparedness should Rafael Nadal be in desperate need of a hitting partner. I have seen no white knit shorts at the French Open, and relatively few ball caps. They’re outnumbered, or nearly so, by white and tan Borsalinos, given for free to those in the ritzier sections.

The players seem to take their fashion cues in Paris from the crowd as well: subtle style, with class rather than glitz. The opening of the French Open has been uneventful for the top men's seeds, per usual, with the only notable upset occurring in the fashion world. Last week, Novak Djokovic announced that he had signed a five-year apparel contract with Uniqlo, a Japanese clothier you’re obsessed with if you’re young and into bright colors and live in New York — or anywhere in Asia — but otherwise probably know nothing about.
