One thing I learned from our travels this summer is that you will be better off if you travel light. You don't need five pairs of shoes unless you are a celebrity that needs a different shoe to complement your outfit for every day of your vacation. A shoe for walking and one dress shoe should be enough. As for clothes, pack separates that can be worn with each other. When partnered with different colored pants and some accessories, it would look like a completely different outfit altogether. You should also choose a luggage that is sturdy yet light, something like the Swiss Army luggage. I know there are some luggages out there that already weighs more than 5 lbs. even when empty. Packing light is more important now since airlines are already charging passengers for their luggages.
