No one really cares if you do tbh.
The moment you are self conscious about it and people who want to mock you (if you are talking about school, since its where ppl actually even bother) see you like that they will make fun of you.
I've wore all kinds of video games, movies or franchises in high school, college, etc. Friends consider it a trait, and the rest wont care as most people dont even know what it is in the first place. My girlfriend always took my shirts randomly if she didn't want to wear something more apropriate (as in clothing for dates or important occasions) and she never knew what they were and no one cared about it either, in fact she still wears them at home or in summer.
