Serena Williams cruised through her opening U.S. Open match against Maria Sharapova, and her apparel became a big topic of discussion along with the speedy win in straight sets.
And as usual, her outfit sparked a debate. Many loved the bold look.
Others thought it wasn't her best -- and one Twitter user likened it to a scuba suit.
The 2018 U.S. Open runner-up was previously penalized for a "Black Panther"-inspired bodysuit at Roland Garros for the 2017 French Open.
Williams's 6-1, 6-1 victory against Sharapova marked the 19th consecutive win against the Russian tennis player.
Post-U.S. Open competition, Williams' fashion will again be on display, this time for her S by Serena label FW19 runway show on Sept. 10.
