Here is a super cool vest. Can't quite read the tag, but it's probably a blend of materials. Steel blue with black lining. Five button front with a pocket on each hip. It looks almost brand new. It's in excellent shape with lots of life left! Here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 21"

Armhole 10"

Length 24"
