As a rule, dress in Israel is extremely informal: casual for daytime, informal for evenings. Bring lightweight clothing in the warmer months, and layers for the winter weather, i.e., sweaters, jackets with zip-out linings, a rain poncho or raincoat to keep warm and dry. Modest attire for visits to religious sites is required (no sleeveless tops nor short-shorts for the ladies); some sites require head coverings for the ladies. Wear comfortable walking shoes (break them in before you come to Israel) and bring swimwear for a dip in the Dead Sea and any other swimming you may enjoy. In Jerusalem or other hilly areas, a light jacket is recommended, even during the spring/summer.
If you require special medications, we suggest that you bring them along with you in their original prescription containers and pack them in your carry-on luggage. Keep a list of your medications and dosages with you as well. Not all brands of medicine are available overseas should you need to refill your prescriptions.
