SOLVED. YA/ Coming of age book with a Poetry format. I read this book in 6th grade so it had to have been published before June 2014 I can't remember the title or the author I've been trying to find this book for ages with no luck. [s]

A specific plot point is when the main character is shopping for Halloween costumes with her mother. The girl wants to buy a little black dress and go as a beatnik, but her mother tells her no and picks out a dress covered in roses, telling her she can go as a rosebush. They buy the dress but the girl comes back later and buys the black dress as well she has her mother believe she is going as the rosebush but changes at her friends house. After the Halloween dance she is waiting for her mom and is groped by an old guy at her school so she forgets she didn't change back to the rose dress her mother picks her up, sees what she is wearing and slaps her across the face. I don't really remember what happens after that
