After being introduced during the 1800's, baseball uniforms became widely popular in the United States. Their popularity even increased further when various major league baseball teams started to add their touch of personalization. The first sign of customization that was noticed on baseball uniforms was the addition of stripped lines. Initially, these stripped lines were made so thinly that fans were hardly able to see them. After a few modifications were brought, the baseball uniforms of certain major league baseball teams displayed clearly visible stripped lines.
