Men's Button Down Shirt McCall's M6613

This project was a long time coming, but I finally finished it a few weeks ago. I think I bought the pattern LAST October, completely inspired by Katie of Handmade Threads. She has sewn her husband a whole bunch of these shirts. (Also, jeans. Her sewing is amazing.)

The pattern is McCall's 6613. I made A.J. a size large. After a lot of measuring and even tissue fitting, I added length to the sleeves. In the end I'm calling this a "wearable muslin" because the sleeves are too long and the front and back could actually use another inch for his taste. He is 6'6" for reference.
