Where is this image from?

Hello all! ^^

I'm new to the community and I'm wondering if someone could tell me where this scan is from? I'm aware that it's from a magazine, I just don't know which one it's from. Image is here courtesy of moe.imouto.org.

Am planning to cosplay that version of C.C and it would only be proper that I know which version I'm cosplaying haha...

Thanks a lot! ^_^
