In August, 1861 newspapers throughout the South published a call for the people to make up as many jackets of brown or gray mixed homespun jeans as they could for the troops: "lined throughout,
with side and vest pockets." Also long in the body, coming four inches below the waistband of the pants and large enough to be worn over the vest or outside shirt.

Variations on the "side and vest pockets" for the jackets abounded...
Stripes on trousers were pretty common for Confederate soldiers too. Union troops mention many of the Confederates in the west in early 1862 wore plain homespun trousers, "made military" by the addition of a black or colored stripe.
From Fort Donelson the prisoners of the Army captured there in February, 1862 were for the most part by then in citizens' clothes, "having no military mark except black stripes on the pants." [Guernsey, Alfred Hudson,
