Travel clothes

I looked through the travel section, but did not find what I was looking for.

I’m going to South East Asia in April and May. I need new clothes to travel. I like the idea of travel clothes that are made to dry fast, breath well and that don’t wrinkle, but I find the price too high and the clothes not very stylish. So I’m looking for what kind of fabrics would have these same properties and what type of store can I buy them from (since outdoor stores all seem a bit expensive).

I’ll need socks, underwear (that stay in place, any girls have a favorite brand they’d like to share?), a shirt, 2 t-shirts, a hat, a sports bra, a belt and a bikini. Maybe even a knee-length skirt and 2 camisoles. I’m kind of aiming to not be dressed like a Magellan model, but still a bit less casual than the traditional tourist t-shirt, short shorts and socks in sandals. Somewhere in the middle would be great. :)

All recommendations, tips and links are welcome. Thanks in advance.
