Sometimes, an outfit is just not working. And that was the case with a former U.S. Open champion on Monday.

During her first-round match at the U.S. Open, Bianca Andreescu had some issues with the skirt she was wearing, and let the chair umpire know about it.

"I mean, it's not my fault. It's Nike's fault," she told the chair umpire.

"I need to go," she said when given permission to change. "This is really bad."

The Canadian told reporters after that wind gusts were yanking her skirt up, affecting her shots.

"It was just bothering me on some forehands. I just felt like it was kind of coming up a bit. Obviously the wind didn't help," she said, via EuroSport.

Andreescu also apologized for what she said about the clothing company.

"I could have definitely used a different choice of wording. So I apologize to anyone I disrespected. I love Nike and I hope I can be with them for the rest of my life," Andreescu said.
