The Best and Worst Dressed Tennis Players at the 2016 Summer Olympics

Tennis players who participated in the parade of nations during the opening ceremony of the 2016 Olympics wore the same outfit as their compatriots.

However, most tennis players have individual clothing contracts and wear their own kits during matches. 

So who wore their country's colors best? 

No player gets to pick the country colors. However, how they choose to wear them separates the best and worst from the rest. The best Olympic outfits reflect national pride yet preserve the player's individuality and style. 

While there were few plain awful outfits, those who made the worst dressed list missed the mark on what the Olympics are all about: playing for country. If a neutral fan in the stands can't figure out exactly what your country's colors are, then that's an Olympic fail. 

With national pride in mind, the following are the best- and worst-dressed tennis players at the Summer Games in Rio.  

Honorable Mention Worst: Madison Keys

Madison Keys' outfit is OK. But she gets an honorable mention for worst because if it weren't for the little flag logo on her top, it would be hard to know she played for the red, white and blue. 

So many countries incorporate those colors into their flags. However, wearing some obvious form of all three hues is sort of standard dress code for U.S. athletes. The neon green and orange on her sneakers are far more prominent than any red and white. 

Honorable Mention Best: Serena Williams

Williams is wearing the same style dress she wore at Wimbledon. It's also the same deep blue on Keys' Nike dress. However, Williams added patriotic accents to her outfit. She wore a Stars and Stripes hair scrunchie, red hair band and even red, white and blue fingernails. On nail is a replica of the U.S. flag. 

That's the way to represent.  

Worst: Heather Watson

The British went all out with the team colors. No problem figuring out which country Heather Watson is playing for. She's got Union Jack stripes on her wristbands and a royal crest on her chest.

However, this is a bit overboard. The Telegraph ran a story in April about backlash against what some called "horrendous" outfits. 

Best: Venus Williams

Leave it to veteran Venus Williams to show off simple elegance in this red, white and blue dress she designed for her EleVen clothing line. 

When she moved, the dress flowed like a flag. She doesn't need a flag logo for you to know who she's playing for. 

Worst: Jo-Wilfried Tsonga

Where's the Vive la France in this outfit? Jo-Wilfried Tsonga could have just worn his Wimbledon kit. The little French rooster logo is a nice touch. But why go all white when you are representing the French flag? 

Best: Kei Nishikori

Kei Nishikori displayed his Japanese red and white in style. Just like the Japanese flag, the center of Nishikori's kit is bold and red and surrounded by white. The red-and-white shoes complement the polo and well-tailored shorts. 

Worst: Jamie Murray and Andy Murray

Back to the Brits. The doubles duo of Jamie Murray and brother Andy Murray are wearing outfits that are all kinds of bad. Andy opted to wear the Adidas brand, even though he's an Under Armour athlete. At least he's wearing the Under Armour shoes. 

Last year at the U.S. Open, Adidas tweeted a picture of Murray still wearing its shoes while under contract with Under Armour. 

Perhaps Under Armour should tweet this pic and be thankful it's Adidas' logo on those horrific shirts. 

Best: Rajeev Ram and Brian Baker

No Bryan brothers, no problem? Their Team USA replacements, Rajeev Ram and Brian Baker, looked awesome in their well-coordinated kits.

The white caps, navy blue shirts, shorts and red shoes worked well together. And so did they, by winning their first-round match. 

Worst: Sloane Stephens

Sloane Stephens gets credit for having U.S.A. in bold letters across her chest. However, the royal blue, ultra revealing cutouts and geometric pattern made for a hodgepodge of an outfit. 

Best: Ana Ivanovic

Adidas may have misfired on the British outfits, but the ensembles made for several female players were right on target.

Ana Ivanovic, Angelique Kerber and Garbine Muguruza represented Serbia, Germany and Spain, respectively. But they all wore this similar red outfit with their country logo. Australia's Sam Stosur and Daria Gavrilova wore the same outfit in green and yellow. By far one of the best looks on the ladies. 

Best: Rafael Nadal

Like Serena Williams, Nadal wore an outfit he has donned at previous tournaments. This NikeCourt Rafa Challenger collection has become his signature look. Why not? It looks great on him. The two tones of red on the shirt and sneakers and the yellow bar across the chest and his country's logo makes it clear he's playing for Spain.
