Look of the Day: Federer in sleek purple

Your resident Spin keeper once came off the court at the tennis club where he is a member and was immediately accosted by a university player 10 years his junior. "I like your jacket," the NCAA player said of his Puma zip-up. "Purple: The color of royalty." It was a quirky, funny quip. Memorable.

That's Roger Federer: Regal world beater and now again also a purple people eater. Or at least one who munches on foes also in the Top 8, judging by his sharp 6-3, 6-1 deconstruction of Janko Tipsarevic today at the ATP World Tour Finals in London.  
The Spin relishes Fed's look today, all crisp lines and perfect cut and with the best collar detail on a pro tennis star's polo this entire season. It doesn't hurt that the color—whether vivacious violet or unassuming plum or another hue—is your Spinmeister's favorite in the world's own Crayola box. And Federer is hardly alone in looking amazing in these shades. One quickly turns to another top-tier champion, one of the sport's greatest of all time, for more outstanding fashions with a purple motif, both on and off court. Yes, for the wrongs or seeming wrongs that Serena Williams has perpetrated at times, she sometimes goes so right, and in the sartorial realm.  
What say you to Federer's WTFs attire—best dressed at this season finale?
