Logos and uniforms of the Boston Red Sox
The primary home uniform for the Boston Red Sox is white with red piping around the neck and down either side of the front placket and "RED SOX" in red letters outlined in blue arched across the chest. This has been in use since 1979, and was previously used from 1933 to 1972, although the piping occasionally disappeared and reappeared; in between the Red Sox wore pullovers with the same "RED SOX" template. There are red numbers, but no player name, on the back of the home uniform.
Road uniforms 
On December 11, 2008, the Red Sox unveiled their new road uniforms, as well as alternate home and road uniforms, to be worn beginning in the 2009 season. The gray primary uniform features the word "BOSTON" in blue lettering across the chest and includes a "Hanging Sox" patch on the left sleeve. The player's name on the back, along with the uniform number, is in blue. The road uniforms paid homage to the Red Sox road uniforms used in the 1930s-1960s, and later in the 1980s, with "BOSTON" in block lettering. From 1972-79 (pullovers) and 1990-2008 the 'BOSTON' lettering is red with blue trim, and the font is similar to the home uniforms. The player's names were only added in 1990 when the previous road uniform was unveiled.
Alternate Uniforms 
The Red Sox alternate home uniform jersey is red and worn with white pants. "RED SOX" is displayed across the chest in blue lettering outlined in white. The team wears red undershirts or sweatshirts and solid red stockings at home. Like the regular home uniforms, it does not feature the player's name on the back, with numbers in blue with white trim. The uniforms are worn on Fridays.
The new alternate road uniform is a combination of gray pants and blue jersey with "BOSTON" in red lettering outlined in white across the chest. The numbers and name are also in red with white trim. They are also worn on Fridays.
Other alternate uniforms 
For the St. Patrick's Day game, the Red Sox wear bright green jerseys with "RED SOX" in white letters outlined in red across the front and the "Hanging Sox" logo is displayed on the left sleeve. While the other uniforms all use blue caps, this alternate uses a green one matching the uniform shirt. This uniform made its regular season debut on April 20, 2007 to honor former Boston Celtics coach, general manager and president Red Auerbach, who died during the previous off-season. A similar green uniform was worn June 20, 2008 to celebrate the recent Celtics victory over the L.A. Lakers in the NBA Finals. The uniforms had a white stripe down the side and the team wore their normal navy caps. Additionally, the Sox wore a variation of the standard uniforms for Earth Day 2009. The uniform featured a white pullover shirt with a red under shirt and the team name in green. The uniform trim featured green piping along the pants and was finished out with the traditional red socks. Lastly, the hanging Sox logo was modified to feature a green recycling symbol around the logo.
On April 20, 2013, the Red Sox wore home white uniforms with "BOSTON" written in red letters and no outlines on the front of the jerseys instead of the familiar "RED SOX", to honor the victims of the Boston Marathon bombings, which took place earlier in the week.
The Red Sox typically feature a navy cap with a red "B" in ornate lettering. This has been a Red Sox standard for a majority of their existence, though during a majority of the 1970s the caps were red with a blue brim, and the "B" in blue with white trim.
In 2009, the alternate "Hanging Sox" logo caps were unveiled, and were paired with the alternate uniforms. However, during the 2010 season they reverted back to the regular "B" cap regardless of what uniform they wear.
Socks and sweatshirts 
From 1936–2002 (with the exception of the 1974 alternate home uniform), the club sported blue undershirts or sweatshirts and tri-colored stirrup stockings, with a red anklet and two white stripes on a navy blue background on the upper sock. In 1974, the team wore red sweatshirts (and solid red stirrups) at home and traditional blue sweats with tri-colored stirrups on the road. Since 2003, the team has worn all-red stockings with both their home and away uniform sets, along with red sweatshirts, with one exception: as part of the 2009 logo and uniform redesign, the Red Sox initially wore solid blue stockings and sweatshirts with their road uniforms. The changes drew some criticism from fans for being too similar to the Yankees' uniforms, and the team switched back to red sweatshirts and stockings after their first road trip and the remainder of the season. While Curt Schilling notably wore stirrup stockings during his Boston career, most players have abandoned stirrups for full socks.
