History of the Continental Army Uniform
During the Revolutionary War, uniforms evolved quickly. On November 4th, 1775, the Continental Congress established brown as the official color of American uniforms. Brown never really caught on with the troops, however. Officers generally preferred blue, and by 1778, so did the members of the Army.
On March 23, 1779, the Continental Congress allowed General George Washington to establish the first official American uniform and style. General Washington selected blue as the primary uniform color. Uniforms were to be lined with red or white fabric, depending on unit type. Infantry uniforms were lined with white, while artillery units had their uniforms lined in red fabric. The supply of fabric and labor did not allow every member of the Continental Army to receive a uniform. With the overall challenge of obtaining and distributing critical supplies, uniforms were just not considered a high priority.
