One aspects that I want to give to my story is that. Between the late 2000s-Early 2010s, Mu had given the mission to redesign the entire Cloths to give them a more modern look.
As such things changed like: When a Saint puts on his Helm/Crest/Diadema thingy, a retractable battle mask is activated to not only protect the identity of the Saint but also to protect the face from many stuff.
The female Saints have the usual porcelain mask of neutral expression but the males could have variations like: Visors, masks without any facial features and only lenses, mouth plates, etc. Also the Saints that have lenses could retract to match the expression of the wielder (Like 0-0, >8, O-o, etc)
Also the under suits beneath the armors changed. As here it represents because of the rank.
Bronze=Color in the neck, torso, shoulders, gloves and boots. While the arms and legs were color black.
Silver=Fully black suits with some details of grey in some areas.
Gold=White suits with black gloves and boots.
Also the colors of the Silver Cloths are, well, silver for the most part and have secondary colors that is the issuer favorite (Like Shaina could be purple, Marin could be light blue, Seika could be red, Shun be mangers, etc)
