A recoloured version of the Baron Samedi outfit. Pieces are available as a random item from the Halloween 2014 mission reward/item shop bags.
Items are not bound until used so they might be on the auction house after Halloween. Can be found on the auction house as “Samedi Coat, black” etc. When placed in the dressing room, the names will change to include Baron for males, Baroness for females.
Note: This set does not include black shoes or top hat, the full set image uses Corbie Topper and Baron Samedi Shoes.
Thank you Chosen-Blood for the screenshots!
