Billy Reid Charcoal Bond Peacoat from last season, worn a dozen times. The charcoal version was 100% wool last year (they now make it with a blend). I'm a 38-39 and this fits me fine with enough room to layer.
The arms were tailored and now measure 24" from the shoulder seam. There's enough material to take it out an inch (see picture).
Price is $415 shipped to the continental US, paypal preferred.
