Clothing
For matches a player the tradition is “whites” although that is changing and becoming club colours instead. It’s normally a club blazer (optional), white long trousers and polo shirt (sometimes with a tie) for men and polo shirt and skirt or slacks with optional blazer for women.
For casual play follow the club rules, but many clubs will be a white shirt or blouse, grey trousers or skirt or grey shorts with white socks.
