Tips for a successful book event

Now remember, this is my first book so I am a complete novice when it comes to this promotion stuff. Yeah, okay, I'm a novice when it comes to most anything related to the books except reading and writing.


Does anyone have any tips on what to do or not do for a successful book event?


Like, do I have to dress professionally? ew! What can I say, I am jeans girl.


Or do I set up a table and sit behind it? That seems kind of impersonable and I always like the events where the author reads an excerpt from the book - or maybe from an upcoming book.


Send your ideas, please.
