Iodineman Costume ideas needed

My girlfriend gets the biggest kick out of calling me "Iodineman" because I am always talking up Iodine to people. We talked about trying to create an outfit for me for Halloween last fall but I was too busy to create something. But it will come to fruition at some point or another I am sure.

So, any ideas?????

I am thinking purple with yellow-brown cape and boots and utility belt and maybe a yellow-brown "I" on the chest.

Various types of Iodine in the utility belt and maybe some slips of paper with the benefits of Iodine listed that I can hand out to people.

Any other ideas out there?
Please put your silly hats on......
