This may sound like a strange holiday, but it's really about celebrating the freedom of working from home. If you work from home you can totally work naked and no one will care. If your job allows it, this is the day you should work from home and dress however you want. That can mean staying in your pajamas all day or just going for 100% nakedness. It's totally up to you! If you don't have the freedom to work from home, you can still celebrate by just dressing a little more casually than you usually do. Enjoy whatever freedom you can get!
