From, here are the shawl collar field shirt jackets in the F/W2009 collection.  I’m not sure if any others will be available, but right now I’m thinking about ordering either the indigo on indigo or the dark chambray version.  The black canvas version seems to be made from a vintage fabric and is a little bit more expensive than the other two.
