Khaki and black striped shirt with black shell

Khaki and black shirt is somewhat like thin sweater material, and the black shell is built-in. This looks really good with khakis for a nice work outfit. It's in great condition. The front shell is 18.5" and the back of the sweater is 29" from neck to hem. The front of the outer shirt goes straight down then tapers into the length of the back. The sleeves are 3/4 length and gather at the top to make them look a bit fancier.
