Throughout history, the Kháng people often used items collected from the forest or woven products to exchange for fabric, pants, dresses, and clothes from the Thái people. Consequently, their clothing is similar to that of the Thái people.
According to Khang beliefs, both men and women should own an Áo dài to wear on important occasions such as weddings, festivals, and Lunar New Year, and to keep for burial. Therefore, the “Áo dài” is considered a key element in the traditional festive and wedding costumes of the Kháng people.
The “Áo dài” (uốp lường) is tailored in a five-panel style from indigo-dyed cotton fabric, with a length of 95–100 cm and a width of 55–58 cm. The two front and back panels are of equal length. The additional front panel has a small pocket (thong toác uốp), a round collar that is 3cm high, and is fastened with five copper buttons on the right side. The dress has a deep slit of 50–55 cm. The long, narrow sleeves have a width of 12cm. Nowadays, this traditional costume is rarely worn. They only wear them for receiving the bride and for burial ceremonies. Many young couples no longer use this type of attire on their wedding day.
Shoulder towel (khan muốn): On special occasions like weddings and festivals, especially during feasts, Kháng men often use a shoulder towel, which is also considered a handkerchief. It is made of white cotton fabric, measuring 55–60 cm in length and 40cm in width. The two ends of the cloth are embroidered with decorative floral patterns, featuring a central trunk with symmetrically branching limbs. At the top of the branches are small flowers, canarium shaped or square.
