I'm doing a "quarantine" theme this year, and wanted to have some HAZMAT guys walking around, but I didn't want them to have the bright yellow HAZMAT suits you can find online.
So, I went to Lowe's and grabbed some disposable paint coveralls, and after a few quick steps, turned them into some pretty awesome looking HAZMAT suits. The look is topped off with an amazing gas mask I found on ebay.
Here's a quick video I made about it:
(And yes, I know the suit is WAY too big on me. I'm not the one who will be wearing it, but still wanted to show off the completed costume)
