I have a cuestion how can i improve my outfit, i want to wear it on halloween, what can i add or remove to make it more faithfully until halloween, everything is modern except the coat that is around 1910

Those are a Diesel pants that was from my father, around 90's, i like them but it's a kind of difficult to combine with other clothes, i only use white shirts and black boots/shoes when i wear them, what would you recommend to combine?
