A number of players have debuted some fresh looks for the summer hard-court tournaments. Andy Murray has shed his skin-tight Adidas T-shirts for a more casual look, Milos Raonic is wearing his heart on his chest and, somehow, Rafael Nadal's shorts have gotten shorter.
Here are some of the best and worst summer kits that debuted over the last two weeks.
Andy Murray: Gone are the slim-fit shirts that he wore since last year's World Tour Finals, which did a great job of showing off his pecs but probably weren't flying off the shelf with the weekend warrior set. (Matthew Stockman/Getty Images)
Eugenie Bouchard: The 19-year-old Canadian looked great in this Nike kit, which Madison Keys debuted two weeks ago at the Bank of the West Classic. The skirt has a nice "poof" to it, too. Is that a fashion term? It is now. (Andy Lyons/Getty Images)
Milos Raonic: These shirts, emblazoned with the maple leaf, flew off the shelf when Canada hosted its Davis Cup tie earlier this year, and Raonic decided to rock it at his home tournament, the Rogers Cup, this week. In case you're asking, this doesn't violate the tour's rules regarding sponsor logos, because it's considered part of the shirt's design. (Matthew Stockman/Getty Images)
Venus Williams: Her 0-6, 6-4, 6-2 loss to Kirsten Flipkens in Toronto was ugly, but her pink EleVen dress was not. (Andy Lyons/Getty Images)
Juan Martin del Potro: The beachy board shorts look is perfect for summertime. (Matthew Stockman/Getty Images)
Li Na: What are you doing, Nike? Don't take away Li's perfect polo shirts! (Andy Lyons/Getty Images)
Rafael Nadal: Count me in as part of the anti-short shorts camp. (Matthew Stockman/Getty Images)
Victoria Azarenka: Azarenka pulled out of Toronto with a lower-back injury, but she debuted this new Nike outfit last week at the Southern California Open. The shift top looks pretty comfortable, to Nike's credit, but it looks awkward on Azarenka. (Joe Scarnici/Getty Images)
Ana Ivanovic: The dress is standard Adidas fare, but in the heat and humidity of summer, the dark colors make the dress look hot. And not in a Paris Hilton kind of way. (Andy Lyons/Getty Images)
