NWOT Brooks Brothers Cotton Khaki Sport Coat.    Two button, Double Vent, Patch Lower Pockets, Pick Stitching, Lightly Structured (No shoulder padding).  21 inches across chest at armpit, 18 inch across shoulders, 24.25 sleeve, 29.5 length at bottom of collar.  I would sell this for considerably more if it had brand labels.

I bought this sport coat from Brooks Brothers.  It is a sample with blank labels, pictured.  So it does not have a brand on it and it does not have fabric content.  In my opinion it is cotton, a tight weave.  40R is the size that almost all samples are made in, and this measures to roughly a 40R, maybe a 39R.  I am guessing that it is imported.

Use measurements to predict fit.  If you don't understand measurements then google these terms:  "How to measure a jacket Andy".

I combine shipping.
