As I have advised you previously, pick a Campaign and base your troops around that.
Saratoga British uniforms are unique and never worn anywhere else, so be aware of that.
The '68 Warrant Uniforms were mainly worn at Boston/Concord/Bunker Hill.
As the War progressed, uniforms adapted and changed.
Shorter coats, round hats (with one side turned up) and "overalls', instead of stockings became worn.
The War in the South offers you many more choices. Especially, if you plan to use Cavalry!
Best advice,,,,,,Think before acting (or buying).
What do I want out of this?
