I call cheating. This is clearly Billie Piper's twin, Not Billie, and she was jealous she was not in Doctor Who, so she dressed up like Rose to fool people into thinking she has made a stellar, highly convincing cosplay. It's obvious. NO one can look that accurate to Rose Tyler... no one.
That's a wig? It's fantastic! I had never seen a so realistic one before... Excellent job with this cosplay... you even look a lot like her, especially when you smile... you'll defintely be one of the best Rose Tyler's coser ever!
