The black and white uniform is the standard apparel worn mostly by Dreu-kin. The outfit contains an under layer, a simple black t-shirt, and shorts that reaches down just over the knee joints, and an outer layer which contains the top and bottom patterned in black on the sides and back, and white on the front center. Each uniform uniquely tailored to each individual, in size, and to the individual. The suit was designed to not only identify personnel, but also for individual comfort, as the interior of the suit is made to simulate an environment separate from the immediate space around them (e.g. freezing cold for ice dragons). This prevents things such as too many fire dragons in a single room from over heating the space they inhabit, and maintains room temperature more easily. The clothing also is made of special materials that are resistant to ripping or tearing, and do provide minor amounts of protection against sharp impacts.
At large, clothing is not something dragons tend to buy since nudity is a culturally accepted norm of society, but rather clothing tends to serve more practical purposes such as ritualism where applied, and the reasons listed above. It is also the reason for existing clothing to look somewhat bland or unvaried.
