The pictures above are of the 1883 Browns that finished second in the AA, the poor 1884 Browns, and the 1885 championship Browns. The 83 and 85 Browns wore all white uniforms while the 84 team was wearing all black (or I guess it could be a dark gray or brown).
The 84 Browns, wearing those heavy, dark uniforms, had the worst record of any Browns team from 1883 through 1890. I honestly believe that those uniforms had to have played a part in it.
I can imagine Comiskey going to George Munson and saying "Look, I know that Von der Ahe's latest mistress designed these uniforms. But only a crazy man would go out and play baseball in the hot St. Louis sun while wearing all black. Talk to the boss and get us our old white uniforms back."
