Help me please!!!!!!!!!!!!!!!!!!! Thanks?

Hey! Well I'm going to a huge bonfire tonight! What should I wear?!?! I'm wearing dark jeans and blue plaid flats or red flats. What kinda top should I wear? I was thinking a loose tunic with a lace cami under it? The stores I can go to are Pacsun, Von Maur, Buckle, American Eagle, and Vamity! Please nothing over $50! Thanks! Oh and what jewelry!? I'm preppy!
