so I was browsing the web for Connor concept art and I found this: the one I want to focus on is the one on the far right it is concept for an outfit that never appeared in game but it looks very French looking and has some similarities to Arno the character from Assassin's Creed V so this is possibly where they got the idea and mixed in a bit of Aveline's outfit from AC Liberation into Arno's outfit too as the shoulder pads on Arno's outfit are very similar to Aveline's outfit and Aveline was a French African Assassin.
