First post here, looks like an awesome forum and I'm looking forward to reading and posting. Anyways, I am trying to expand my work wardrobe past basic suits and ties and looking to get some sport coats and dress pants to go with them. First question - what are some common color combinations that people use to match coats and pants? I've been told black coat with gray/charcoal pants, as well as the opposite of that. What are other good combinations? I'd like to stay away from navy blazers and khaki pants as I'm just not a fan of that particular look. My main question is this - do the sport coat and pants need to be of the exact same material? Would it be a major error to wear, say a 100% wool coat with a wool/poly blend pair of pants? Also, what color/type of jacket goes best with a nice, dark pair of jeans? black? any specific material? thanks!
