User blog comment:Gorberus/Mikuru's lookalike/@comment-4817-20120522122855

The woman on the left doesn't really look like Orihime. Is that fanart? But more importantly, they're anime characters. Anime is an art style and any two characters can look alike, especially if they share certain attribute.

That's why anime characters often have oddly-colored hair, hair decorations, and distinctive outfits, because otherwise you can't tell them apart.
