This is a gorgeous shirt from Brooks Brothers.

Made of non-iron Supima cotton, it's a beautiful ligt lavender.

The shirt has a straight collar, single-button barrel cuffs, slim Milano fit, left chest pocket, and a squarish tail. 

This beautiful shirt is NEW, without tags.  It is a store pull because it is mistagged. It is guaranteed to be unworn, authentic and absolutely perfect.

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

The neck measures 17 inches from button to buttonhole.

 The sleeve length is 33/34 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.
