It's annual closet cleaning time, and making decisions on things I have barely worn over the last year. This jacket is smooth worsted wool. The opposite of a casual, textured coat that would pair with casual khakis. Most dress pants are grey. However, shades of grey on grey is very tricky, and can look like a mismatched suit. With navy dress pants, a grey jacket completes the "security guard" look. Awful. The only other thing I can think of is blue jeans. But, I'm not a fan of the "suit coat and jeans" mismatch of style and texture. There is a lesson here. I bought this jacket so focused on achieving a great fit, that I didn't even think what I'd wear it with. As a result, I have never worn it, b/c it doesn't go with anything in my closet. Do you own a grey sport coat? If so, what kind of pants do you wear it with? Pictures?
