This is a gorgeous shirt from Vineyard Vines.

Made of cotton, it's a beautiful plaid in orange, blue and green.

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

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

  Marked M. I have measured the shirt and: 

The neck measures 14.5 inches from button to button hole.

 The sleeve length is 32/33 inches from mid-collar to the end of the cuff. 

Across the back, laid flat, the shirt measures 18 inches armpit to armpit and 30 inches from the collar seam to the bottom of the back tail.

Fit can vary by size, even within the same brand. Please compare my measurements with a shirt that fits you well to ensure the size is right for you.
