Question:
Can one wear, say, a navy pinstripe jacket (fine, subdued, gray stripes) with gray or khaki slacks? Or does a pinstripe require matching pants?

Answer:
I would go for the matching pair of pants. Usually you would just get the plain blue to go with Khakis. I think of Italiano Mob when I hear Pin Stripe and Khakis are not in their wardrobe. I would go for the match.

Answer:
Thanks. That's kind of what I thought.

Answer:
khakis? no
jeans? yes
