The Right of Adornment was a tradition held by members of Romulan society.
It dated back to the founding of the Romulan Star Empire and served a similar purpose to a Right of Standard. A fleet or unit that was awarded a Right of Adornment were allowed to design an original fabric pattern for their uniform tunics. Whilst most tunics employed a variation on simple geometric pattern, the shapes and colors change from one type of uniform to another. Though it was considered archaic by certain progressive commanders and politicians, most officers appreciated the symbolic importance the tradition held throughout the Star Empire.
The standard uniform had a checkerboard woven pattern that represented the bulk of the command fleets of the Romulan Star Navy. However, the Othan Fleet employed a colorful interweaving of squares and rectangles whilst the Kassus family fleet used severe bronzed triangles with crimson highlights.
