Each department will also have its own uniform. The law department used to be light blue with no collar, but since 2009 it has become purple with collar. It looks good, but it's a pity that it's very similar to the Department of Economics and Trade, and the changes are the same, so many people think it's all for the sake of changing similarities, so they changed their clothes. Unexpectedly, they changed them together.
Some classes also make uniforms, but there are too many kinds.
