This classic button-down shirt is made of 60% cotton and 40% polyester.  I machine-washed it in cool water and dried it in a cool dryer, and it dried nearly wrinkle-free as shown.

The shirt has black buttons and include 2 buttons on each sleeve cuff for a more custom fit at your wrist. There is also a smaller button in the gauntlet opening in the sleeve to alleviate any gapping there.
One extra button of each size is included, sewn into the button placket.
The back has a yoke as well as a center pleat for ease of movement across your back and shoulders.

It is 34 3/4 inches long, measured down the center-back. It is 57 inches at the chest/armpit and 57 inches at the hip area.  The sleeves are 21 inches long, measured under the arm.
