A few weeks before the release of Dragon Quest XI: Echoes of an Elusive Age, Square Enix announced that there will be a free outfit or costume from Dragon Quest VIII that the hero can wear right from the beginning of the game. While the outfit or costume is good only in the early parts of the game, theres a way to improve it further that can later be used at the latter part of the game.
