Clothing
Both men and women travelers can typically dress however they ordinarily would in their own countries. Contrary to popular belief in the West, women can wear T-shirts and long sleeves are not always required until going to a religious location.
Both Muslim and Orthodox Christian religious places advise visitors to wear head coverings. When visiting Christian holy sites, dress as you generally would in the West; avoid wearing shorts inside of churches. Particularly in Christian neighborhoods, many local ladies dress in Western clothing. Both men and women frequently wear shorts.
Be aware of your surroundings; it is advisable to dress more modestly outside of tourist-heavy regions. If a woman wants to draw less attention, she should wear shirts that reach her elbows and don't show any cleavage. All across Damascus, regular t-shirts and jeans are perfectly acceptable wear
