Ignoring the issue of the points, Rio walked towards the store which was issuing them the essentials of first years - the uniform, weapons and the books needed for basic studies of the first year schedule.
Talking about the uniform of the academy that he received. There aren't many differences between the uniforms of various students of all the years. The academy only gives out simple t-shirts, shirts and jackets to everyone. Boys and girls have similar designs too. (Obviously except the obvious differences in making). Whenever you're in class these clothes are mandatory to wear.
(As for pants, there's no rule. One can just wear whatever color or style they have or want. Shorts and half skirts aren't allowed, because it isn't a beach and horny holiday. Academy also gives pants, so if you got none - we got you.)
