Formal attire to go meet and give my resume to McDonald's manager.

So after months of trying to get a job this will be my first time meeting and talking to a manager and the only

issue is that i dont have any clothes that falls into "formal attire" the best i can do is to wear a blank black shirt, my straight cut black jeans and a pair of converses. Will that suffice po ba?? Im 18 and fresh out of highschool.
