Stunning Brooks Brothers men's sport coat from my personal collection. It no longer fits me, so sadly I am passing it on. It’s truly my favorite sport coat.  Although this coat hasn't been for sale 

The fabric is a beautiful yellow herringbone, with light blue windowpane overlay.  It was sold by Brooks Brothers probably 15 years ago (around 2010).  A similar coat today (Brooks Brothers, 100% silk, made in Italy) would probably be $700+ or so.  This is a real bargain if it fits you!

Crafted from premium quality 100% silk fabric and expertly tailored in Italy. It is perfect for spring or summer. Single-breasted, two-button front and notch lapel.

Check the measurements against your own favorite sportcoat or dress coat.  This coat fits me like a 38 Short, and I think the measurements are close to a 38 Short, although the interior pocket tag is "36 Shor"  The measurements are approximate:

Chest (flat across the front): 19.75"

Waist: 18"

Shoulders (flat across back at widest point: 17.5"

Sleeve length (outside of sleeve from sleeve head at shoulder to wrist): 23.75"

Length (base of collar to hem on back): 29"
