This DLC adds several items seen worn by NPC's in the game as purchasable items in Elihal's shop in Novigrad. This started as just adding more masks, but now also includes a few hats. I tried to keep it limited to items that have yet to get this kind of treatment in other mods/dlc's. They equip using the Mask slot.

They are sold by Elihal in Novigrad (the same shop that sells quest related masks), and Sjusta in Kaer Trolde Harbor (the barber near the inn). Following are exactly what is sold using their item codes. You should be able to use the additem(' ') console command to instantly put them in your inventory.

Known Issues:
soft body physics for straps do not function, I've yet to figure out how to use the games "wdyng" files.
There is some minor clipping for some items that can't really be helped. I edited some meshes as best as I could with my limited skills.
The face bandana clips with beards, for now just shave until I figure out how to hide the beard while wearing it.

Possible Future Updates:
Fix straps
Add at least a few more hats and items
Replace the multiple masks with 1 single paintable version of each, as well as make some existing hats paintable
Tweak some of the icons so they fit a bit better in the game, not a priority
Add new hair variations for some of the hats (like the bandana), low priority

Installation:
Just extract the zip files contents into you dlc folder.
Uninstallation:
Just delete "dlcnewhatsmasks" from your "dlc" folder. Please note that doing this will remove those items from the game.

Special thanks to the mod Hoods (https://www.nexusmods.com/witcher3/mods/4242)
and its creator TheRealArdCarraigh
Studying it helped me figure out how to remove hair when equipping hats, check it out for more hats and hoods
