FIFA banned Cameroon from wearing sleeveless jerseys
After the team won a major trophy in basketball-style vests, football's governing body ruled the kits illegal for the 2002 World Cup.
In early 2002, the Cameroon national football team debuted a radical kit design that lacked sleeves entirely. Known as the Indomitable Lions, the players were surprised to find the basketball-style vests in their dressing room, but they quickly embraced the look. The team went on to win the Africa Cup of Nations while wearing the jerseys, sparking a fashion trend across the continent.
