Onboard a cruise liner, you can dress however you please. Vacationers come from all over the world, and most people are accustomed to shorts and T-shirts. As a rule, the majority of people aboard cruises come from the United States and Europe, so feel free to pack the usual Capri pants, tank tops, polo shirts and cutoffs that you'd wear to any other devilishly hot place.
As usual, you'll want to bring comfortable clothing for daytime activities and dressier outfits for special occasions, such as nice dinners and dances.
Fashions are remarkably diverse in Egypt, but it's prudent to dress conservatively. Men should wear long pants and sleeved shirts. Women should expose as little skin as possible. Most traditional women in Egypt wear head scarves, as this is a sign of modesty. Tourists need not wear head scarves, but it is not advisable to expose shoulders, hair or necklines. This will attract lots of attention, and some people may even grow hostile.
During the days, the Egyptian sun can be punishing, so although the culture demands that you cover up, you'll want to dress in the baggiest, most breathable clothing possible. Light cotton is your best bet. As you'll notice, traditional Egyptian fashion favors baggy pants and full-body tunics. There is no reason to "flaunt it" in Egypt.
Most people are surprised how chilly Egypt can get after the sun goes down. The cold is largely perceptual; after a very hot afternoon, cool weather can seem downright frigid. But the Sahara's actual temperature can drop to 50 degrees or less, even in the warmer months. Take care to bring a sweatshirt or light jacket, just in case you're out late.
If you find yourself short on suitable clothing, don't worry. The Cairo souks (marketplaces) are packed with elegant garments, and if you know how to barter, you'll find some incredible bargains.
Keep in mind that Egypt has attracted visitors for thousands of years, and the nation thrives on its massive tourist industry. Beachside resorts are generally modern, comfortable and Western in nature; in most places, you can stroll the private beach in a string bikini with impunity, although it's best to ask resort managers about appropriate dress just to make sure. Nobody knows propriety better than the locals.
