Bueller?...Bueller?... Anyone?

Am I dreaming the impossible dream? I just want to find some nice pants for work, preferably ones that shed wrinkles (and won't end up looking like you pulled them from the bottom of the clothes pile, did a sniff test, and threw them on, even though they were fresh, clean, and unwrinkled 2 seconds before). OK, that part sounds do-able. Plenty of 'dress' pants are wrinkle-resistant.

Here's the kicker - the pants have to not make me literally sweat my ass off in the heat and humidity of Houston. Most 'dress' pants seem to be made with some sort of polyester/rayon/spandex mix. Last time I tried to wear one of my dress pants to work this summer, I had to turn around after stopping for my ususal caffeine/coffee fix and return home to change pants. I was going to lose several pounds of water if I didn't.

I need some cotton or natural blend fabric that's been treated to shed wrinkles. At the very least, a manufactured fabric with some breathability. Am I reaching too high? Am I dreaming too big? Anyone have some suggestions for brands of dress pants?
