Those are not kilts.

I don't even see a proper apron. They look like sport skirts. Er, I mean sport kilts. On the first one, that's the BACK of the kilt. See the belt loop in the middle? Most of it's not even pleated and the surviving pleats have wandered off to better places.

Those look an awful lot like the school girl uniform skirts that I see getting passed off on ebay as kilts.
