This is a really nice shirt from my own closet. The size tag is missing (it must have bugged me and I cut it off), but I'm as medium as they come and it fits me very well. The 17/35 measurements are my own.

Fairly small red plaid, with black and white also in the mix. No front pocket, which is how I think such shirts should always be made. A spare button is provided, in case one gets lost or broken.

Measurements, laid flat and not stretched:

Shoulders (between tops of shoulder seams) 19 inches
Chest (pit to pit) 21.5 inches
Bottom opening 22 inches
Length (from top of collar in back, to bottom) 31 inches
Sleeve length (along top, from shoulder seam) 26 inches

Material: 60% cotton, 40% polyester

Let me know if you have any questions!
