can i wear gir merch if I’ve never watched invader zim?

Hi, new to the culture(s) of scene, scenecore, emo, etc. there’s an event that I’m going to today and i wanna dress up with the gir outfit that i have but i’m afraid people will think of me weird considering i’ve never actually watched the show. Also i don’t have my hair dyed, idk if that’s necessary. Lmk asap plzzz
