If you want the Skeleton Crew outfit in Assassin’s Creed Black Flag Resynced, you need to buy the Deceased Crew Attire from a vendor on a small island near Salt Key Bank.
It’s a Ship Vanity and costs Animal Bones, so the real challenge is collecting enough of them to unlock it. Once you have the bones, head to the vendor, make the purchase, and your crew’s appearance will change into a skeleton-themed look that stands out on the open sea.
