Pack a bag! Start a list of what you want to bring and what you need to buy. Pack at least a few days in advance. Packing at the last minute will ensure that you forget something important and pack a bunch of stuff you will never need. Actually I start collecting things about a week in advance, adding and eliminating items as I go. I prefer black clothes for traveling. It is so easy to dress up and dress down with black. Black pants, jacket, and shoes go a long way. Two pair of shoes should do it. One for walking and one for dressing up a little. I think comfortable sandals can be dressy and good for walking. Use scarves and colorful shirts to jazz up your outfits.
