So let me explain--- this suit will not have that colo you can imagine this suit with ur fav color that is gonna be in the story as (f/c) and the same goes with the designs on your body and the flaming stuff on your feet, hands and hair. You don't have that stick you have these around your waist.

You have 20 of these baby's around your waist and since your quirk is Iron or metal manipulation you can make them float and when your quirk activates your hair starts to levitate and your eyes start glowing of (f/c) the same goes with the designs that are in your body but when you are not using your quirk those designs turn in to your body natural color. And in cold places you get stronger and your skin gets very cold that anything wet can stick to you.
Downfall
of this quirk is that you can't pass your limit start bleeding from the nose and it will be risky using the 100%. In warm places you can't used the 100%of your quirk.
