George boots and Chelsea boots are also acceptable. Socks should be black or grey. Spats were once frequently seen with morning dress, but are now rarely worn and, by 1939, the practise of wearing them was considered to be almost extinct. Accessories Headgear In the Commonwealth of Nations, traditional black, or grey (less formal, but becoming more widely accepted), top hats are considered an optional accessory for weddings. However, hats remain compulsory in the Royal Enclosure at Royal Ascot. Pocket square A pocket square should always be worn with morning dress. They may be made from linen, cotton, or silk. Whilst a simple white linen square with rolled edges is classic, they may instead be a solid colour or patterned and should always complement the neckwear. However, although it is very common practice in wedding parties, many style authorities do not recommend wearing a matching (i.e., identical) pocket square and tie, as it tends to look contrived, draws attention away from the wearer's face, and displays sartorial uncertainty. Pocket squares with a solid colour should generally be paired with a patterned tie (and vice versa) and should not share the same base colour. In other words, the solid color item should be in a color that is not the dominant color of the other. It may be puffed or folded into a square, single-point, or multi-pointed style folds. Puffed pocket squares work well with softer materials such as silk; other folds tend to hold their shape better when more structured materials such as linen are used. Decorations The wearing of decorations, orders, and medals is uncommon with morning dress. An invitation will generally indicate whether or not they should be worn and, in the United Kingdom and Commonwealth realms, are more common for religious services or public functions of official significance. Up to four stars, one neck badge, and full-size medals should be worn with morning dress; when a neck badge and star are worn together, they must be of different orders. Etiquette: "morning dress" Men wear morning dress when members of a wedding party. In common with court dress, mess dress, and white tie, morning dress is for prestigious and important social occasions. Despite its name, morning dress may be worn to afternoon social events before five o'clock, but not to events beginning after six o'clock in the evening; the term "morning" is best understood as "daylight".
