I'm going travelling at the end of May. I'm spending 6 months visiting the USA, Japan, Vietnam, Cambodia, Thailand, Malayasia and Singapore.

Obviously I'm not going to be able to take a great deal of items with me, but what clothing essentials would you recommend?

I tend to wear skinny jeans but in these hot, sticky climes, I doubt they'll be the comfiest... I like the more indie/rock look of early Alex Turner, and my budget is at a minimum: anyones sartorial wisdom would be greatly appreciated!
