The World Cup final feature will feature Germany in their traditional white tops with white shorts and Argentina in blue tops and blue shorts. Germany is the designated home team for the match so they get the choice of which kit to wear and because they wear white, Argentina have to wear their change kit.
In past World Cups, Germany wore black shorts with their white kits, however FIFA have required that they wear light colored shorts with their white tops so they have worn white shorts with their white tops this tournament. Argentina's blue change kits used to feature white shorts at times, but they have been asked to wear dark shorts with their change kit so they are in all blue now.
Germany wore their white kits for their first two matches of the group stage, a win over Portugal and a draw against Ghana, and their first two matches of the knockout stages, wins over Algeria and Belgium. They wore black kits with red horizontal stripes for their other two matches.
Argentina will be wearing their change kits for the first time. They have worn their classic light blue and white striped shirts for each of their six matches so far. The only thing that has changed is whether they wear white or black shorts.
