RAD uniform
The standard RAD uniform is worn by students attending the Royal Academy of Diavolo.

The uniform is an off-black, double-breasted, military-style jacket with a belt, the right side has a half shoulder cape with a badge of the RAD initials, and a red cloak on the left side. The sleeves are long with a quilted pattern and small gold teardrop beads in the intersections, and a solid black band around the wrists. The pants are an off-black with a vertical red stripe. The dress shirts are a teal color.

The dress code seems to be lax for most of the students are allowed to wear accessories and wear any tie they wish (or choose not to).

Diavolo’s uniform is differently colored for it is red instead of black, the badge ribbon is blue rather than red, the cape is black instead of red, and his dress shirt is black instead of teal.

Because of the lack of female characters in the game, a uniform for female students hasn't been shown.

 * According to the devilgram story of The Glory Days, RAD has existed even when Lucifer and the others were still angels.
