What sort of clothing is acceptable? Do women have to wear a head scarf?
Generally, the more conservatively you dress the better. In very touristy places such as Kuta in Bali, you can essentially where what you like. In places where tourists are uncommon reserved dress is encouraged. If in doubt try to emulate the locals in the area you are. Although Indonesia is an Islamic country, women are not required to wear a jilbab (head scarf). This does mean that women dressing immodestly will provoke a greater reaction than men doing so.
