This is a cargo style, but I recently got a pair of Rigg work wear pants made by Wrangler from kingsizedirect.com and I really like them. They are made from Cordura if I remember correctly and look to be well made. There's even a reinforced pocket edge on the right side to protect the pocket from a clip.
Anyhow, I wore them to substitute teach the other day, and I think I'd feel comfortable wearing them in most casual/dressy situations, cargo pockets and all.
They're on sale now for $32.99...I paid $54!
Especially at that price, I'll be getting more.
