Question: are black dress pants business casual?
Answer: Pants: Nice trousers or pressed khakis. Khakis should be flat-front for a clean, fitted look -- not those rumpled chinos you roll up and wear to the beach. Pants should be cotton, although wool is fine; silk, rayon, and linen are no-nos. Wear pants that are black, brown, grey, khaki, or dark colors like blue or green.
