Doc Martens for a cocktail theme wedding?

Hi all. I don’t own a suit or any dressy clothes for that matter. I mainly wear (band) hoodies, (band) tshirts and jackets with jeans or chinos. The only semi nice shoes I have are a pair of 1460 Doc Martens (not the most formal), but I wanna know what to pair them up with to at least kind of fit the theme of a cocktail style wedding!
