Jack A. Weil, a garter salesman, breezed into Denver in 1928 in a new Chrysler Roadster to start a new life. He exceeded his hopes and became a king of cowboy couture — almost certainly the first to put snaps on Western shirts (17 on a shirt), and most likely the first to produce bolo ties commercially. His Rockmount Ranch Wear Mfg. Company has sold millions of shirts, including at least one shipment to Antarctica, since it started in 1946. Clark Gable wore one in “The Misfits” with Marilyn Monroe, and Heath Ledger’s shirt in “Brokeback Mountain” — plaid fabric, diamond snaps and saw-tooth pockets — was Style No. 69-39.
