"We love sweater vests and we tend to carry some that are more traditional fair isle and would work nicely under a sport coats OR styles that are derivatives and would look better over a white tee for a casual look. Well... this one is really both. Made of a premium merino wool that is high-twisted for a sturdy, lighter wearing result. in an attractive slightly retro low-contrast diamond pattern. I can think of a dozen outfits that would look so good with this vest."---Greg
