Who could, for example, forget Tomas Berdych's bold, H&M floral arrangement from a year ago in the French capital?
And on the opening day of this year's edition Sunday, Ana Ivanovic donned a black Adidas outfit with nearly knee-high socks designed by Yohji Yamamoto.
Maria Sharapova, like Ivanovic no stranger to magazine covers, opted for something a little more low key when she faced Kaia Kanepi in the first round Monday.
As her clothing sponsor, Nike, put it, her dress "showcases the quintessentially French Breton stripe in a stylish and performance-driven silhouette."
Her choice of attire seems to make perfect sense, since Sharapova must feel right at home in France nowadays.
She is the defending champion at the French Open and has appeared in three consecutive finals, winning two of them.
The Russian had a mostly uncomplicated opener, ousting the injury riddled, two-time French Open quarterfinalist Kaia Kanepi 6-2 6-4 in cool, breezy conditions on Philippe Chatrier court.
Uncomplicated in tennis terms, that is.
