I second the "always natural fibers" rule. I go for linen pants (since they're meant to be wrinkled!), a cotton tank with long sleeved cotton shirt or a cashmere sweater over it. I wore lace-up sneakers on my last flight, but I'm going to go for slip-on sneakers for my next one so I don't hold up the security line with tying and untying my shoes.

I don't understand people who fly in heels or tiny miniskirts and tank tops.

Oh, and Lifeis, the U.S. also has restrictions on liquids. You should check with your country's transportation authority (they probably have a web site) to see if they allow you to take on small amounts. In the U.S. you can take items of 3 ounces or less as long as you put them in a single one-quart clear zip-top plastic bag. That includes toiletries and makeup, but of course that pretty much rules out bringing any drinks through security.
