You'll want the basics, such as underwear, socks, shirts and pants or skirts, but there are other considerations, too. Firstly, some countries may look down on females wearing certain garments, for example short skirts, so research the culture of where you're headed. Any country, no matter how sunny it usually is, can experience adverse weather, so pack rain gear such as Gore Tex pants or a quick-dry polypropylene shirt. Don't forget flip-flops, to wear in the shower or in warm weather, as well as swimwear and related items like flippers.
While you can grab forgotten items at the airport or on your trip, it's more convenient to bring things such as deodorants, toothpaste and toothbrushes with you. A toiletries kit bag will help keep your possessions clean on the road, while see-through sealable plastic bags are useful for getting your items past airport security. Plastic bottles of soap come in handy since your accommodation may not provide it.
You'll need some items with you wherever you go; these include any personal medicines you're required to take on a regular basis, alongside inhalers, contact lenses and eyeglasses. Consider your destination when choosing additional items for protection; if you're heading somewhere hot, don't forget sun-cream of the right factor for you, insect repellents and mosquito nets. Include a first-aid kit, that contains emergency items such as bandages.
Mix it up with it comes to the money you take abroad; as suggested by the Rick Steves travel website, a combination of debit and credit cards with hard cash will see you through. Remember to keep most of your money, whatever form it's in, in a money belt, concealed under your clothes to prevent disaster if your wallet is stolen.
One essential is your passport, even if you're staying in the U.S., which acts as another form of identification, in case your wallet gets stolen. Take other I.D. cards with you too, such as student identification if applicable, and don't forget tickets, including rail passes and flight references, in whatever form you're given them in. Photocopy important documents, like your passport, and then store the duplicate separately. Also, keep the phone numbers of family and friends on you while you're away, just in case, while you need to make a note of your accommodation address. A guide book is always useful, too.
