I started working on uniforms for a regional baseball league starting in 1871.
The initial uniforms will be pretty basic with no team logos until around the turn of the century.
I am planning to make the uniforms regional. The northern teams will have 'proper attire' with players required to wear ties. The southern players will wear military style uniforms. The western players will wear pullover uniforms with string ties.
Couple of samples so far:
Northern Association - Boston Capitals
South Atlantic League - Charlotte Blue Jays
