It seems to be a mask which is attached to a shroud. The shroud is made of what appears to be a very thin, white but nearly translucent material while the mask is a pure porcelain white and featureless save for a single simple eye decoration on the forehead. The shroud, which seems to flow from the edges of the mask, would cover entire body when worn.
When worn everything user can see through the mask is slightly distorted and the colors are significantly more muted. Wearer appears as a skeleton in a porcelain mask.
Apparently any object touched while wearing the shroud will be subjected to some type of psychometry (reading memories of object). Example
