Getting back to the original.
Never liked the small player number on the front under the logo - too Dodgers, who had it at least as far back as the 1950s. The Dodgers introduced an all green uniform, no blue at all, in 1937. The following year, they went back to Dodger blue, and replaced the capital letters DODGERS with the now familiar script.
I think the Mets uniform with the multicolored stripes down the shoulders and pants was the ugliest.
Who remembers the weird Chicago White Sox uniforms of the 1970s?
