I'm always fascinated by the differences in packing strategies by different people. One of the biggest packing differences are between men and women. I travel enough to have stopped trying to take half my closet and 22 pairs of shoes. I have realized I don't need that much variety, especially since I rarely would use that much I brought. Even packing just about the bare minimum now, I find I don't wear all of it. If you look at your patterns, you may find you're the same, or you're a guy that could use a little more variety, because you actually pack less than necessary. You probably don't need a tuxedo on your trip, but is is possible that a sports jacket would help you out in some situations?
