I recently added a new Engineered Garments western shirt to my ongoing collection – a red mini pane on soft grey flannel. It’s available at Jack Straw in Seattle as part of the Fall/Winter 2010 collection, along with another version in solid white broadcloth.
Tattersall plaids from MAPS – no known stockists in the U.S.
Another one from Doo-Bop in a navy mini pane – Legion in LA is so far the only stockist that I’m aware of for this version in the U.S.
They’re continually difficult to find, so do not sleep on picking one up.
