Men: A black, navy or dark-grey suit, single- or double-breasted – the fabric can have discreet stripes. A potential waistcoat should be made of the same fabric as the suit or its colour should be in harmony with the suit. White shirt. A tactful tie or bow tie that works with the suit (not white). Dark socks and shoes with slim soles.
Women: An elegant black (dark) dress or a light two-piece (skirt or trousers). Light shoes. Socks should complement the dress, e.g. the colour can flatter that of the shoes.
Men: A black tailcoat with matching trousers that have satin on the side seams. The coat is not buttoned. A black waistcoat (also in the evening event, if only men are present). A white starched shirt with a stiff front and collar. A white bowtie. No handkerchief at daytime. Black socks and shoes with slim soles (not patent leather at daytime). No wristwatch. For outdoor clothing, a black coat or cape, a white scarf and white gloves.
Women: A black, high-necked, long-sleeved dress or two-piece (skirt or trousers). Black gloves. Graceful shoes.
