Vietnam Era Army BDU
Vietnam era Army BDU, with slim fit and slightly extended 70's collar. Soft, strong fabric, that doesn't wrinkle. A perfect shirt. These are the gold standard. Super hard to find, so get them while you can.
The added southwest fabric is just beautiful. The fit is completely opposite from the woodland fatigues. With the woodland, I say order one size smaller than normal, with these I say get one size bigger than normal.
