Almost 21

My 21st is only months away and ive already started the planning
but knowing i wont have a whole lot of cash but want to make the place look fancy im struggling on idea's
im having it at my local and which means that it has to look respectable.
apart from the obvious table decorations what else can i do.. i really want to have a playboy theme if possible but i can not find playboy party decorations to save my life...
if people could give m some idea's that would be awesome..
