“..... The women, especially from Kota Belud, make beautiful embroidered panels sewn into their long black wrap-skirt. Traditional headgear worn by almost every indigenous group known as kain dastar is one of their specialty. The Binadan (from Kudat) is well known for their kain pis, a richly embroidered one-meter piece of two-facing cloth”.
"Satu ciri pakaian tradisi masyarakat asli yang sangat ketara ialah penggunaan tanjak yang dibuat daripada sekeping kain dastar berukuran tiga kaki persegi yang ditenun oleh suku kaum Iranun di Kota Belud. Apabila ia dilipat dan diikat, kain hiasan kepala atau siga ini dipakai oleh kebanyakan kaum asli Sabah.."

In the past it was not unusual for Iranun men to claim to be Bajau when they mixed with the wider society who may know the name Bajau but not Iranun, or who still insists on calling them ‘Ilanun’ with its negative connotation. However, according to some of the old people, in the very early days, the Iranun and Bajau did not intermarry. In fact according to their oral tradition, before the colonial days, in early years, the Iranun have always been from the ruler tribes and some considered the Bajau or Sama people below them. Until today, the Iranun have various ‘strata’, rankings, which show up when it is time for a person to marry. (see marriage section below) Today these two groups do intermarry, however, earlier many of the Iranun did not tend to live in mixed villages. There are some Iranun villages where the majority of people are still only Iranun, with a very distinctive language.

You will see even the locals, some Iranun themselves too, can't even spell their own name. "Irranun" phonetically would have to be pronounced "Ir- ran - un", but it is pronounced I-ran-un. The Iranun need to rise up from their lethargy and their pretention to be Malay - to who those in WMalaysia will say - no way they are not us - we are the true Malay because of our ancestors etc.. Govt says 'you are Malay based on Malay language, culture & religion', however, that is all politics -- when it comes to other areas, to identity then no, the groups are thrown back.
Seriously from what one can see/study, the Iranun traditionally had an extremely rich culture and they are the ones who have had great influence on the other groups. Why do you think it's the Iranun woven head gear that all these groups wear, using different ways of lipat them, for their own ceremonial occasions? Obviously since it's already used in ceremonial occasions as long as the older generation of Bajau and Dusun can remember, it's been around a LONG time. Today, even at the committee meeting Rita was saying to me the Bajau are weaving -- well, we know they learned it from the Iranun -- and unless the Iranun are willing to stand up and point out traditionally they are the ones who had this beautiful skill/craft, then again the Iranun children, the next generation are POOR, poor -- having nothing -- and is it any wonder they are ashamed to admit who they are? The Iranun, though a smaller group, have had influence on these larger groups.
