"Elton Academy Uniform's Hierarchy" 

The only differences in these uniforms should be the color of the cape or the badge. 

Some students had navy cape and black cape with the same white trousers or skirts, and some students also had silver or golden badge shining on their left chest. 

Ainsley didn't pay too much attention to the badge and only saw the different color of the uniform and thought that it should represent the different grades? 

The white one was most likely to be for junior high school students and the dark navy uniform was for the senior high school. 

But what about the black cape? 

Ainsley didn't know about this, so she didn't inquire, but soon, as she passed by some big restaurants, she saw small children wearing the same type of uniform as those outside but their size was indeed smaller. 

These children's clothes were surprisingly maroon or purple, not white, navy or black like the older students outside.
