After sparking sexism debate for giving Alize Cornet a code violation because the Frenchwoman temporarily took her Lotto Barre Top off during her first-round defeat against Sweden’s Johanna Larsson, the US Open apologized and changed their attire policy, which now reads:
All players can change their shirts when sitting in the player chair. This is not considered a Code Violation.
We regret that a Code Violation was assessed to Ms. Cornet yesterday. We have clarified the policy to ensure this will not happen moving forward. Fortunately, she was only assessed a warning with no further penalty or fine.
