i need some new pants. i'm working with a relative to get a small food business going so i can't dress up. all i have are dress pants and 2 pairs of jeans. i've never really liked jeans, though, so i want to buy some pants that i won't mind getting dirty, but that are not jeans and aren't chinos or khakis. any ideas? i'll be wearing them with polo and short-sleeved button front shirts.
