Looking over the pictures of Starfire for Red Hood And The Outlaws #1, I see that her hair is not a consistent length, either. Even if you ignore that big shot with her hair curving in a graceful circle as she arches her back, her hair is hanging down past her ass, the small of her back, or mid-back, depending on how she's posed at that moment.
I think I'm over the mortification of Rhapsody's Amazing Changing Hair. Of course, Starfire is at the beach, and Rhapsody's adventures are underwater, and humidity does make your hair do funny things, right? ;-)
And some of you are probably wondering, "WHY are you noticing the length of Starfire's hair?!?"
