Is this actually from Shakugan no shana hoặc did someone just rip off shana's uniform?

I was đọc this bài viết about the differences between the anime aired on ti vi and the dvd release and the changes and extra content that goes into it. I scroll down the comparison pictures and I see this girl is wearing Shana'a uniform and I'm wondering if this is legit Shakugan no shana hoặc an amazingly similar uniform in a different anime.
