Consularis, as a retired head of state position, takes the stance of all retired positions, such as Emeritus (Retired Emperor) and other retired veterans; You may choose to wear the uniform of any rank you held during your service to the Empire.
All Ceremonial Uniforms are undergoing review, and if you have any questions or suggestions please speak to a voting member of the council of honor, or make a properly formatted proposition for vote (Greg can help you there!) to put forth before the council.
Magistrates uniform has not been discussed upon the Council of Honor in any form at all due to the fact we had no active magistrates; You will need to bring that up with a Senator (Myself, Eban, Tyr) or the Head of State (Greg) or the Praetorian Prefect (Kelfer), Or the Emperor and Empress. If you have suggestions for uniform, please note that ceremonial uniform must be all of one piece (I.E. Not a mixed set of elf, human, and samurai armor) and must be wearable by all (Exception is gargoyles as currently gargoyles are not allowed due to their inability to wear uniform. Therefore, all ceremonial armor must be human armor without exception, as elf armor is race exclusive.)
Hope this clears that up, if not, talk to me! Thanks!
