England are in all-red, again, tomorrow.
FIFA World Cup 2018 Rules and Regulations 48.2 states that "Each team shall inform FIFA of two different and contrasting colours (one predominately dark and one predominately light kit) for its official and reserve team kit (shirt, shorts and socks). This information shall be sent to FIFA on the team colour form. Only these colours may be worn at the matches."
Given that England's official colours are (according to the FA and Nike) White/Navy/White and Red/White/Red, the continuing use of red shorts is puzzling. There is nothing in the rules to permit the use of a third kit. Either England's official "Team Colour Form" included the red shorts instead of the white ones, or the rules are not worth the paper they're written on and are simply being ignored. Given that the red shorts aren't even commercially available, I suspect the latter.
Are these "Team Colour Forms" published? Colombia are another case in point - their official colours (again, according to the kit manufacturer) are yellow/navy/red and blue/orange/blue, but they wore white shorts in the World Cup whenever possible, and the orange shorts never saw the light of day. Odd.
As an Englishman, a pedant and a traditionalist, I find all of this very disappointing. We finally have two great-looking kits and neither of them are being used. Hopefully we'll beat Sweden and play Russia in the semis and France in the final, playing both matches in white/navy/white!
