This is about a movie I've seen a while ago, but now I can't remember the title. It's about a nerdy guy that meets a girl and she changes him, he convinces him to change the way he dresses, the way he looks, to even fix his nose. She is supposed to debut an art exhibition, and everybody is there, and it turns out that her work of art is the guy himself, he's a case study, she shows before/after pictures of him, of the way he changed. Can you help me?
