Dimitrov, Kerber, Bouchard and more enjoy IMG party

Petra Kvitova was another big name at the party. The two-time Wimbledon champion won a tricky first round against Magdalena Rybarikova.

Eugenie Bouchard stuck out from the sea of cocktail dresses in a blue spandex outfit more appropriate for a spinning class. She opens the first Slam of the year against Peng Shuai, who had to win a wildcard to get into the main draw of the event.

Monica Puig enjoyed herself as well, though she would lose her opener to Anastasia Pavlyuchenkova in straight sets.

Day Two of the Australian Open kicks off on Tuesday with Serena Williams, Novak Djokovic and Noami Osaka all on the schedule.

IMG knows how to throw a party—just ask any of the players that are represented by them. The global sports management company hosted its annual Australian Open launch party at Crown Towers Melbourne on Sunday.

Guests included tennis power couple Stan Wawrinka and Donna Vekic.

The Swiss has a challenging first round ahead of him against Ernests Gulbis while Vekic beat Kristina Mladenovic on Monday.

Two-time Slam champion Garbine Muguruza stopped by. She starts on Tuesday against Zheng Saisai.

Reigning Wimbledon champion Angelique Kerber didn't miss out on the fun.
