Does that weird translucent thing the girls wear serve any specific purpose? So, in Mahouka Koukou no Rettousei (i.e. The Irregular at Magic High School), the girls' school uniform incorporates this strange translucent cape-like feature. See, for example:





That translucent cape-thing is very unusual as far as school uniforms go - I've never seen anything like it. Does it serve any particular purpose in the context of the show (like, it makes you better at magic or something), or is it just ornamental?
According to this tweet:

It's an a camisole-style lace garment can be worn under the jacket, it's as an optional accessory





Therefore I don't believe there's functional purpose to it.
