fashion of betawinese

This is the formal dress of Jakarta's native inhabitants, the Betawi people; the same kebaya, only none of the varieties is shorter than hip-length; none of them is transparent; and the way the Betawinese wear their 'kain' (that's the Betawian and Indonesian word for the Javanese 'jarik') is simple and straight -- while the Central Javanese jarik is wrapped around the body like a cone seen upside-down (it tightens in 'descending order'), the Betawinese wear it loosely, the width is the same all the way down, and it stops right before the ankle, so it's shorter than the Central Javanese 'jarik'.
The kebaya is V-necked, usually collar-less, and similarly closed with a brooch. No scarf is worn around the shoulder. Instead, the scarf is worn on the head, as 'kudhung' in Javanese, or 'kerudung' in Betawinese and Indonesian; signifying the Muslimness of the wearer (the Betawinese have been traditionally more into religion than the Central Javanese).
In Yogya, 'kudhung' is worn instead of a scarf with kebaya in formal occasions by some of the women since 1990's, as a sign of faith in Islam (which is anyway not so 'covering' as the Islamic headgear 'jilbab').
