So I don't know if this is okay but I had two ideas kind of along the same (but different) lines, one being the modern COVID-19 protective suit and the other being the Plague doctor. (I had some ideas if there was to be any kind of event to go with it.) I thought it would be cool if there was "sick zombies" or "sick bats" or something that drop either of these vanity set items and have a chance of infecting you and your NPCs, spreading through them if not isolated. Some of them may die (and drop their special item) but others will just look sick for a little while and recover. I was thinking if there were any kind of perks to wearing it aside from vanity, it could stop you getting sick and provide some minor defense against poison or something? Short term thing, the zombies/bats would return to normal after a few days or something. When you're sick you just walk and heal a lot slower and maybe get a little green or something for a period of time. (These are lame versions but I'm sure they can look pretty)
