Appropriate Clothing, Jerusalem
Clothing/Shoes/Weather Gear: When visting Jerusalem, you must bring light colored shirts so as to deflect the rays of the sun as it can get really hot since this area the area lies in close proximity to the Judean Desert after all. you can use your walking shorts instead of jeans and slacks but you will not be allowed to enter some of the attractions as they have a strict dress code, specially in Churches and in mosques. Don't wear leather shoes as it would be hard to walk with the leather shoes among the uneven stone pavements along the Old City Quarter of Jerusalem.
If you are like me, you are bound to get lost at least once in your travels throughout the Walled City. Good walking shoes are a must.
Toiletries and Medical Supplies: If you like to use a washcloth, pack some. Most hotels in the Middle East do not provide them.
Clothing/Shoes/Weather Gear: If you want to see Christian and Muslim Religious Sites you will need to wear "appropriate" clothing. I was told, Long Pants for men. NO SHORTS, even in hot weather. I was also told, in the Jewish religious sites (the Western "Wailing" Wall) - they allow shorts. BUT NOT on SABBATH!!! So, to be safe, bring long pants. And to be safe, bring some long sleeves also. And PC or not, they are pickier with women - so women, make sure you are well covered. (not just a Muslim thing) so you won't be denied entry into the significant, religious sites. The HEAD also need to be covered. So, if you don't want to share lice with the loaned head covers, bring a baseball cap. Helps anyways in the bright sun.
Even if you are not planning to visit any of the Holy places in Israel, it is advisable, especially for women, to bring one ' coverall' outfit. By this I mean a long sleeved top ( that doesn't reveal too much neck) and a long skirt or trousers, not tight clothing. Wandering through the old city in revealing clothing will bring you unwanted attention, especially in the Arab Quarter and from Hassic (orthodox) Jews and orthodox christians. Women have been spat at, insulted and even stoned on odd occasions for this. At the very least you will cause extreme offense, DON'T DO IT!
Men visiting the religious sites will also be expected to cover their legs and arms. Both sexes will need headgear, a hat or yarmulke ( jewish skull cap ) for men in synagogues and a scarf for women when entering mosques or synagogues.
