Which bag should I bring to the DC Law School Forum?

I have three options which all have pros and cons. Which one do you think is the best option for me?

Option A: a small roll-y carry-on bag
pros – won’t wrinkle my suit, easy to carry the tons of paper materials I will be getting
cons – nerdy as hell, may be hard to maneuver down the aisles

Option B: a backpack
pros – comfortably distributes weight of paper materials
cons – may wrinkle suit, hard to put on and remove at each table

Option C: a large tote bag
pros- classy looking, easy to slip papers in and out of bag
cons – weight of papers solely falls on one shoulder
