Found what seems to be a bug with the outlaw motif (chest piece).
I got lucky and looted this of a random mob in one of the delves.
After crafting a robe (light armor) and a shirt/jerkin (also light) it appears they are the same. It is not possible to craft a robe (the item is called a robe, but it in fact is a jerkin).
Below a screenshot of the outlaw Robe...
Is this intended ?
