The official
Code Geass website has links to "APPAREL" and "ACCESSORIES" now, but neither are functional yet. You know what this means... Official Ashford Academy uniforms and "Eleven Scum" T-shirts are coming your way!
Actually, some company(s?) have been producing Ashford Academy uniforms since the start of the show, but the site chooses one official supplier... I'm hoping for
Cospatio.
