World No. 31 Jelena Ostapenko received a caution from a Wimbledon chair umpire concerning the visibility of her sponsors' logos on her gear. The incident occurred after Ostapenko, the former French Open champion, had previously appeared on court with the logo of British supermarket Tesco visible on her kit during her first-round victory over Harriet Dart.

Following her defeat of Antonia Ruzic, Ostapenko was approached by the chair umpire and another official while she was seated. The discussion focused on her sweatbands, which featured a large black logo. Ostapenko expressed confusion regarding the inquiry, and Wimbledon staff reminded her that the tournament's rules on sponsors differ from those of the WTA and the International Tennis Federation (ITF).

When questioned about the exchange, Ostapenko stated, "I don't know (what the issue was), maybe you have to ask the chair umpire. Maybe they didn't like something, I don't know." The deal with Tesco, the British supermarket's delivery service, was reportedly for that specific match.

Wimbledon's dress code mandates strict adherence to an all-white aesthetic for all attire. Rule number four of the tournament's guidelines specifies that "Colour contained within patterns will be measured as if it is a solid mass of colour and should be within the one centimetre (10mm) guide." It further clarifies that "Logos formed by variations of material or patterns are not acceptable."

Ostapenko has been a notable figure at the Championships this year, previously drawing attention for her sarcastic applause directed at the crowd after Dart secured a third-set break, an action that was met with boos from spectators.
