Participants should be as formally dressed as possible. Specifically:

For male delegates: suit ( coat, trousers, dress shirt, waist vest, tie). Alternatively, dress trousers with a shirt and a coat. Jeans and athletic footwear should be avoided.

For female delegates: blouses, pullovers, suits, shirts, trousers, skirts and dresses (not above the knee).  Comfortable low-heeled shoes are recommended. High-heeled shoes, jeans and mini-skirts are highly inadvisable.
