You need to have played the companion app of AC Unity to be able to wear Altair's outfit. You need to find all the fragments of Nostradamus enigmas to wear Thomas de Carneillon's outfit. You need to finish the solo campaign to wear the Arno Master Assassin outfit. And you need to have played in Initiates to wear Ezio's, Connor's, Edward's and Shay's outfits. Sorry Crimson :/
