Grand Slam are always the most exciting venues for tennis glamour and the US Open is the unofficial fashion queen of all the four majors, so let's see what the best brands put on their brightest WTA stars.

Let's start this fashion overview with maybe not the biggest fashion star, but definitely the player who marked this US Open – Kim Clijsters, whose inspiring career has come to a close at her favorite tournament where she had lifted the trophy three times. To honor the Belgian's last event, her clothing sponsor Fila produced a special collection with a symbolic star pattern.

Ana Ivanovic (who reached her first Grand Slam quarterfinal since her title win at Roland Garros 2008), Angelique Kerber (last year's semifinalist) and Laura Robson (besides Clijsters, the biggest story of the tournament) were all sporting Adidas Adizero. The bright yellow Adidas outfits may have ruled the US Open courts, and the three players mentioned here all played the fourth round, but the next brand we'll cover is clothing all the four semifinalists!

Of course, it's Nike! Champion Serena Williams and Maria Sharapova traditionally have both day and night dresses. Serena wore navy and pink with lime details, while Sharapova went for more subtle tones – liquid pink and solid dark without many loud contrasts.

Victoria Azarenka and Sara Errani prefer separates. The world No.1 is popping in a yellow and black combination, while the Italian, sharing the look with Julia Goerges, wore a pleated navy skirt with pink and yellow stripes and a tank. Read more »

As expected, we enjoyed the concurrent Grand Slam sort-of success of the Serbian sisters for a short time. Second seed Agnieszka Radwanska was a big obstacle for Jelena Jankovic this time, even though the Pole is past the second round at the US Open for the first time in four years, while even before that her results couldn’t match Jankovic’s semis here in 2006, quarterfinals in 2007 and final in 2008. Those days are long gone, though, and today Radwanska converted six of seven break opportunities to eliminate the former world No.1 in straight sets, 6-3 7-5. Let’s see what Ana Ivanovic will do tonight against Sloane Stephens. Read more »

Hardcourt season didn't have a warm welcome in cards for Agnieszka Radwanska. The abrupt switch from grass took its toll on the Pole's body and now she's retired from her New Haven opener with a right shoulder injury. Radwanska, who was top seed at the New Haven Open, is hoping that resting will recover her by Monday and the US Open.

I've been struggling with my shoulder for a couple of weeks now, pretty much since the start of the hardcourt season two weeks ago. I think maybe the change of surface and balls since coming from the Olympics was just too much, and I've played a lot this year as well.

Our guest blogger Omair likes to give WTA players unofficial titles on the account of their performance at big events. Notice how Serena improved from the Biggest Disappointment at Roland Garros, to Grass Empress at Wimbledon, to shortly afterwards become a Golden Empress at the Olympics.

SERENA WILLIAMS – GOLDEN EMPRESS

With her first gold medal in singles at the Olympics, Serena completed her Career Golden Slam, joining Steffi Graf and becoming only the second woman to achieve such a feat. Moreover, Serena did that in style, losing a total of 17 games in six matches. En route to the medal, Serena defeated four players who have ranked world number one at some point (Jelena Jankovic in the first round, Caroline Wozniacki in the quarterfinals, Victoria Azarenka in the semifinals and Maria Sharapova in the final). She also became the only tennis player in history to complete Career Golden Slam in both singles and doubles. With such a strong performance, Serena reinforces her title of grass empress earned during Wimbledon 2012.

MARIA SHARAPOVA, VICTORIA AZARENKA – BRIDESMAIDS

Always a bridesmaid, never a bride. Sharapova and Azarenka were both the victims of Serena at the Olympics, and have combined three wins against her in 21 matches.

Sharapova rebounded strongly from her Wimbledon disappointment, however, she lost her plot completely once in the final and managed to win just one game in the most lopsided Olympic gold medal match.

Azarenka seemed determined to be on the course to win gold, but just like at Wimbledon, it was Serena who stood in her way. Azarenka had a chance to avenge her Wimbledon loss, but went down meekly, winning just three games against Serena. Read more »

In the first round of the Olympic Tennis Event and on the first day in 100 years that rain sent the Olympic tennis indoors, Julia Goerges upset second seed Agnieszka Radwanska 7-5 6-7(5) 6-4.

En route to the victory, Goerges fired 56 winners, including 20 aces, 17 forehand winners, 12 backhand winners and 5 volley winners. Her differential of winners to unforced errors was +31, while Radwanska's was just +3.

To make the win even bigger for Goerges, Radwanska's last tournament and actually her last final came at the same Wimbledon venue this month. (source: WTA Tour, photo: © Neal Trousdale)
