This is a gorgeous shirt from Martin Dingman.

Made in Portugal of 100% cotton, it's a small red houndstooth.

The shirt has a button-down collar, two-button barrel cuffs, a left chest pocket, and a squarish tail. 

This beautiful shirt is NEW, without tags.  It is guaranteed to be authentic and absolutely perfect. 

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

The neck measures 16.5 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 24 inches armpit to armpit and 33 inches from the collar seam to the bottom of the back tail.
