Funny thing: I never marched for either of my graduations in undergrad or graduate school.
What you wear though ought to be comfortable enough to have on underneath those robes, which I’m pretty sure are not-that-breatheable polyester. Depending on where you go to school, it might also be super hot and miserable. Would be a shame to ruin a good shirt and suit with sweat stains.
I would just wear a dress shirt and tie with some lightweight trousers and comfy dress shoes — maybe even bucks. You can always change after your walk to put on a jacket and nicer shoes if you wish.
Congratulations and best of luck finding a job!

At graduation I was wearing a black poly robe and it was 85 degrees and very sunny. I would recommend just wearing underpants in a situation like that. If the weather is better (worse?) wear something comfortable, then change.
Yeah, the entire process seemed really unappealing to me. My parents really weren’t really intent on seeing me walk (for them, the fact I graduated was enough) and I wasn’t too keen on ceremonies. Instead, I chose to get drunk, wake up late the next day and watch anime. There wasn’t a person I knew that graduated in my class that told me “Oh, you totally missed out! You should’ve gone.”
