Petra Kvitova brought a fierce black look to the St. Petersburg player party.
Jelena Ostapenko also donned black for the event—before falling to Kvitova in the quarterfinals.
Black was the color of the night in Russia, as local favorite Anastasia Pavlyuchenkova jump-suited up.
Meanwhile, Sloane Stephens is recharging in Los Angeles, the City of Angels.
Maria Sharapova, like Stephens, is training in California this week.
While this is an incomplete look, and possibly a terrible one, Garbine Muguruza gets props for not being afraid to think outside the box.
