The period from the beginning of 1863 until early 1864 would probably be the time when the southern armies were best supplied during the war. Although captured clothing was still being worn, more troops would be in a uniform of some sort than in the earlier period.
Regiments are probably fairly uniform in either gray or butternut jackets. Since they wear out quickly, pants are still varied.
Equipment is good, being in many cases captured. At Gettysburg, the entire army had rifle muskets. Haversacks are all tarred, blankets are all captured or government issue, and many troops carry captured canteens.
Western armies probably have more butternut uniforms and troops with russet (brown) leather gear as they are farther from Richmond which has first priority for new equipment.
Most junior-grade and many senior officers use plain, serviceable, and indistinctive uniforms.
