Nike Tennis has unveiled the largely classic looks for the lineup of stars on its roster. Roger Federer and Serena Williams, defending champs at Wimbledon, meet up with Rafael Nadal, Maria Sharapova, Li Na, and Juan Martin del Potro—Grand Slam winners, all—to wear a measured but fashionable rack of looks befitting the All England Lawn & Tennis Club.

For one, Fed is back to wearing collars, and for that we are glad. His attire at the French Open left him looking a bit "meh," as the kids say today, and didn't warrant his inclusion on the Spin's best and worst looks list there.  (Expect a return for Fed on our Wimbledon roundup.) Elsewhere in this crowd, Sharapova's chevron skirt sticks out, in the best way, as does the flattering waist on Serena's frock. Both look regal, as they should, with six Wimbledon singles titles between them. Li Na sticks to her polo persuasion, which looks more than comfortable, and Rafa and Delpo's looks fall in line with their wont, as style goes.

It's all perfectly fitting for the occasion at SW19, and with 51 Grand Slam singles titles among them, these Nike athletes will be ready to storm the grass. Whose look do you like most?
