This is a gorgeous shirt from Southern Tide.

Made of cotton with a touch of Spandex, it's a beautiful plaid in red, blue and yellow.

This beautiful shirt is in absolutely MINT condition.   It is guaranteed to be authentic and absolutely perfect. 

  Marked XL. 

I have measured the shirt and: 

The neck measures 18 inches from button to button hole.

 The sleeve length is 37/38 inches from mid-collar to the end of the cuff. 

Across the back, laid flat, the shirt measures 28 inches armpit to armpit and 33 inches from the collar seam to the bottom of the back tail.
