This is a variation on an old outfit I've had my RK in for years, just with the addition of Hunter OD helm and shoulders, the treasure-field cosmetic moneybag, and some boots from Dunland.
Great thing about that cosmetic moneybag from the treasure festival is that it hides your runesatchel when equipped in the cloak spot for RKs. Nothing worse than a runesatchel to ruin an RK's outfit. Even though they are dyable, they often dye funky and just ruin your whole look.
