When not hiding, I can see my gear alongside my description either by double-clicking myself or right-clicking and selecting "look." While hiding, double-clicking myself doesn't do anything, and right-clicking and selecting "look" shows a blank silhouette as if I had no gear attached. The description still displays, though.

As another character, upon spotting the first character in hiding, I am able to "look" and see their gear normally using either method.
