Cosmetic

Click in the dotted square

The term "cosmetic" refers to only the appearance, not the function, of any item. A character can show or hide the appearance of the armor/robes, headware, goggles and cloak they are wearing. Named items have a fixed appearance, while randomly generated items will have an appearance assigned from a fixed pool of appearances (with some limitations).

To turn visibility on/off, open the Inventory screen, and click in the appropriate area - the head to cycle through helmet, goggles, both, or none, the body for armor/robe, and the knees for cloaks.

(Note that randomly generated cloaks that were looted previous to Update 40 (Oct 3, '18) will not have any cosmetic appearance attached to them, so will not be visible.)

There are also many items that are purely cosmetic, that can be placed in a "cosmetic slot" found in Inventory, below he above image, whose appearance will show regardless of what gear you are wearing. The appearance of these items can be turned on/off similarly to the above. These purely cosmetic items are expanded to include weapons.
