Whatever he does decide to wear, it is important that the groom looks his best if only as a compliment to the bride. Once the style of suit has been chosen, the accessories will have to be selected. With a morning suit for example there is a choice of plain collar and tie or a wing collar and stock. A top hat is usually worn with morning dress and should be either black or grey to match the colour of the suit. Gloves, shoes, socks and waistcoat are the main accessories.
Black shoes tend to go with everything and black socks are best as well.
The waistcoat can match the suit or contrast brilliantly, there is no hard and fast rule on this point. Gloves should be cream chamois leather. A cane is never carried to a wedding. Lounge suits may be of any colour from white to black with any shade in between. If colours are chosen however, they should at least tone with the colours worn by the bridesmaids, and if the bride is wearing white or cream, the groom's suit should be white or cream to match to prevent a discordant effect in the photographs.
