Short sleeved shirts with dwarf patterns are common drops from any humanoids all the way from level 5 to level 50 zones. Some dwarf vendors of those that sale gray armour may have them as well. They most probably will be medium or light.
The fury shoulders can be found crafted from Forochel, Enedwaith (OD), Dunland & GR zones. There are light, medium & heavy version.
I haven't seen any short fingerless metalic glove pieces like those in game but i suspect that something similar maybe from the OD sets, probably the medium armour classes, i don't recall how the OD heavy gloves look.
I checked on others photos of the character & those are surely dwarf pants & westernese boots (go by those names in game).
