The Chicago Bears are one of the original franchises from 1920 that helped start the NFL. The Bears have a rich history of great players, but not much of a uniform history.
Team founder, George Halas, chooses navy and orange for the teams colors because his alma mater, the University of Illinois, wore the same colors. The Bears' jerseys went though a series of different looks during the first few decades (shown below). It wasn't until the 1950's that Chicago started wearing the uniforms that NFL fans know today.The C on the helmet is about the only thing that has made any change over the years.
