This is a gorgeous shirt by Ermenegildo Zegna.

Made in Italy of the cotton, it's a blue and white check.

This shirt has a button down collar with hidden tabs, single-button barrel cuffs, left chest pocket, and a square tail with side vents. 

This beautiful shirt is in excellent used condition.  It is guaranteed to be authentic.

  I measure each item before listing it and the measurements for this shirt are: 

The neck measures 15.5 inches from button to button hole.

 The sleeve length is 35/36 inches from mid-collar to the end of the cuff. 

Across the back, laid flat, the shirt measures 23 inches armpit to armpit and 31 inches from the collar seam to the bottom of the back tail.
