Carlsen had initially stepped away from the tournament when he was informed that jeans were not permissible per the existing dress code, which only allowed dark-colored trousers. The situation escalated when he was fined $200 for not complying with the dress standards after wearing jeans of his own choice. The grandmaster had been dressed appropriately with a blazer and shirt but opted for jeans post-lunch. Confident in his attire, Carlsen protested the sudden demand for an immediate change of clothing, leading to his resignation from the championship and a declaration to leave New York.

Responding to the incident, Fide president Arkadi Dvorkovitch announced a revision of the dress code, emphasizing that minor deviations would be accepted, particularly when they comprise elegant jeans that complement a jacket. He expressed hopes that players would maintain the event's formal atmosphere, particularly during the New Year’s celebrations.

Carlsen took to social media to confirm his comeback, stating his intent to play in jeans, underscoring his preference for comfort over rigid traditions within the sport. The 34-year-old chess prodigy has faced scrutiny in the past, including controversies surrounding his high-profile legal battle against accusations of cheating during a match against Hans Niemann. In light of recent changes and the resolution of prior disputes, Carlsen is set to return to competitive play in a style emblematic of his unique approach to chess and its evolving norms.
