The Alka is much more than a mere competition in riding and hitting a steel ring – it also includes the presentation of the uniforms, weapons and equipment of old in all of its splendour.

The alkars and squires’ uniforms stand out with the beauty of their colours, cut and ornaments. In addition, various kinds of richly decorated weapons give to the procession and the competition an even more ceremonious note and significance. The attire of the Alka knight distinguishes itself with its fur busby (kalpak) decorated with a plume (penoć) and its long dolman decorated with silver and gold on the chest. The dolman is deep blue in colour, while the dolman of the commander (alajčauš) is black, short and fur-trimmed. Every alkar wears a sabre on his left hip.

The duke is all in gold. The attire of the duke differs from that of other Alka participants by being made from brown baize, with a red plush waistcoat (krožet) and girdle of golden yellow and red. It is also exceptionally lavishly decorated with gold embroidery, and all of the duke’s other ornaments are gold, as well.

The alkars’ squires wear the most ceremonial form of the men’s folk costume of the Cetina region. Their red caps are wrapped in a peškir with an attached sprig of flowers; they wear snow-white shirts with wide sleeves and, above them, sleeveless jackets (ječerma) made from red baize and decorated with silver plates, buttons and rings; their trousers (gaće) are blue, and they wear a red girdle (pas) around their waist and light peasant shoes on their feet.

The squires are equipped with historic weapons, with long flintlock rifles on their shoulders firelocks and yataghans protruding from the snake’s nest on their waistbands.

In the procession, they also carry a historic shield and two maces.

The mace is a striking side arm with a carved handle and an iron head divided into flanges, which is why the people often refer to it as a flanged mace (perni buzdovan).

The folk costume of the young women of Sinj is also worn and presented at the Alka. The Ethnographic Museum in Split has preserved a unique exemplar of 19th-century women’s folk costume from Sinj, popularly known as the Alkaruša.
