Agnes Monica, the famous Indonesian actress and singer, is given to wearing sexy clothes, whether on stage, TV or advertising billboards -- but not in the provincial capital of Aceh province. Just across from the 19th-century Baiturrahman Grand Mosque is a large billboard that features Monica wearing a headscarf — even though she's a Christian. Also absent is the tank-top exposing her bare arms and navel that Monica wears in the ad for cell-phone service running in the rest of the country.
