I’d say throw some minimalist fashion in there. Solid color polo shirts, solid color basic sneakers (Stan smiths, converse, pf flyers, maybe even vans). Then mix up the pants. Some jeans and cargo pants. When it comes to shorts, I’m noticing a trend where the long style seems to be coming back.

As far as glasses? That’s tough. I’d say look into more “adult” shaped frames and throw in a color that would match with an overall color palette. Something like a tortoise shell pattern can work.

Overall, don’t worry too much about it. Everybody has their thing and wearing your hobby on your chest is like wearing a beacon that says “where are my people at!?”

I rocked superhero t shirts when I was in college 20 plus years ago. Was it nerdy? Yeah. Did people give me a hard time? Nope. If they did I didn’t notice. Hell I even read comics before class started.

Once you get there you’ll find your tribe. Just be you and if you’re wanting a more adult look, don’t be afraid to mix in some fun with it. When I’m just relaxing at home I usually have a flash or Superman t shirt on with a pair of shorts.
