To mark the Cubs’ first visit to Fenway Park since the 1918 World Series, both the Red Sox and Cubs on Saturday night will wear throwback uniforms that replicate the ones they wore 93 years ago.

Here are more details from the Red Sox:

The Red Sox home uniform will be a blank button-up with no lettering and a slight off-white or ivory color. The hat will also have a blank off-white tint, and the socks will be a three-part white/red/white composition. The Red Sox used this uniform and hat combination as their primary home look for most of the 1910s, and did not have any lettering on the front of their uniform for the bulk of that decade and the entire 1920s. The team did not wear the familiar blue cap with a red “B” until the early 1930s.

The Cubs will wear navy blue pinstripes and lettering on a grayish uniform. On the front left-hand side of the uniform, there will be a horizontal outline of a “C” enclosing “UBS” in smaller, navy blue letters. The Cubs will sport a five-part sock with grey, blue, white, blue and grey color sections. The road hat will have a navy blue bill and pinstripes (but no “C” or any other lettering on the cap). The Cubs used this uniform for only one season, as they changed their road uniforms on an almost-yearly basis during the 1910s.

Each Red Sox player will sign his replica uniform after the game, and all uniforms will be auctioned to support the Red Sox Foundation. More information will be announced soon.

There are also plans for additional elements of the Saturday pre-game ceremony and game presentation that will be reminiscent of the fans’ experience in 1918.
