We have decided on a Uniform theme, rather than a strict uniform, which will be used at major public events. The theme is simple, a dark themed outfit, with the tabard equipped, all focus should be put on the tabard and the guild icon. This matches the icon's meaning, "The icon resembles the Holy Templars in the world, a light in the darkness that will spread to all sides of Azeroth."
Examples would be the Deadly Gladiator's PvP sets, which are themed black and look perfect with the tabard.
You will be given enough time to collect your sets, but I expect to use the uniform as soon as possible.
