A full open formal barong in gray cocoon silk, AUGUSTUS carries the EN Barong Filipino name, finished with long sleeves and a chinese collar. Cocoon silk is reeled from the cocoon of the Bombyx mori silkworm, prized as both the strongest and, for its weight, the lightest natural textile fiber. This full-open construction is known as “straight” — a classic barong style with embroidery running in two parallel vertical bands down the front.
