While western visitors are not subject to the same customs as its locals, Jordan is still primarily a Muslim country, so revealing clothing will be frowned upon. In Amman and outside the cities especially, we strongly advise both men and women dress conservatively. Shorts, for example, are very rarely worn by anybody and would certainly make you stand out in downtown Amman.
When bathing by the hotel pool, one-piece swimsuits are preferred to two-piece bikinis although these are still accepted at some hotels. Topless sunbathing is strictly prohibited.
If visiting between May and September, loose, lightweight clothing is recommended. Thick jumpers and coats are essential during the winter months, and hats, umbrellas and raincoats should be in you suitcase if visiting from November to April. Remember to pack warm blankets if you’re planning on spending the night in the desert.
