I will be taking only one cary-on size bag and wanted to pack light and tight to save space. The cloths have to be versatile enough to be appropriate in a wide variety of cultures and climates. They have to be tough enough to stand up to constant wear and frequent washing. They have to be quick-drying for doing laundry in hotel sinks. They have to fit nice, look crisp, and feel comfortable. And they have to be classy! I don’t want to look like I’m living out of a single pack, even though that’s precisely what I’m doing.
