Gap Original Khakis seem reasonably slim:
They're tapered and the hem is just under 9".
I usually wear size-32 pants. The 31 was skin-tight. I picked up a 32 because they were slightly tighter around the butt, etc. than I'd like and I'm hoping they don't stretch too much.
If you're ordering online, note that the inseam is a full 1" less than marked.
