This costume has an opening in the middle and side for easier wearing by the wearer. The frontal part covers the wearer’s abdomen, while the back part is longer going beyond the wearer’s waistline.

Alike the men of Lobou Dusun, the tribe’s women’s costume too uses the weaving method to produce Bayangkis with cotton thread as the main substance. Previously, the women produced the thread by twisting the cotton thread and dip it into a dark plant liquid.

The cotton thread is processed using Gapas Landa or the cotton fruit is basked till dry and the seeds separate. The dried cotton is twisted to become thread and coloured according to the needs of the costume maker.

Originally, Bayangkis had only four colours that are red, yellow, brown and black. The process for producing each colour is also different.

The ober tree bark is used to produce brown colour. Yellow colour is produced by the soaking of the sepang tree leaf and bark. The black colour is produced by soaking the thread into a mixture of clay called ronok, like a thick mud. The colour red is produced by soaking a mixture of tree bark with six types of leaves grinded together till very fine. This mixture is called inabah.

All the colours, except red, undergo the same process with the aim of maintaining the colours, that is the threads that have been boiled together with the soaked water are left for a month before basked in a shaded area till dry.

There are three stages in producing Bayangkis, that are mongoloting, tudungan and mangawol (menurip). Every stage has an important function.

Mongoloting is the process of arranging the thread into the weaving tool, arranged according to the placement and colour to determine the colour group arrangement of the attire. If there was a mistake in the arrangement, the pattern colours would be unbalanced and untidy.

Tudungan is a rattan plait weaved onto the Bayangkis. The costume’s pattern depends on the pattern as produced on the tudungan. This plaiting also functions as a guideline during the weaving process so as to avoid making mistakes during the weaving of this attire.

The mengawol (menurip) is the last process whereby the arranged thread during mongoloting is weaved to become Bayangkis. Tudungan is also used as a guide to produce pattern during the mengawol stage. This cloth is weaved elongated then cut into two and sewn in the middle part.

This costume undergoes changes from the wearing aspect. Originally, it was worn by pushing it down from the head through the opening in the middle of the attire. Only this attire is worn as there is no inner clothing for both men and women. The obou or loincloth is worn by the men and tapi or skirt by the women. Nowadays, this attire is made like a jacket worn on the outside with a black long sleeve innerwear. The loincloth is replaced by black trousers.
