What armor is this called? And where to craft or get it?(picture below of purple armor)

It's called Shudad. People who pre ordered the deluxe edition get it with some other items I think.

The only possible way to get it now is to put up a pre order & you might be very lucky & get it (very much doubt it though). PA will probably release it on the Pearl Shop after a year or so to make some extra cash. They just recently added horse armour to the pearl shop which was supposed to be like a limited edition loyalty point set when we first got Nouver on the Xbox.

Ok, thanks for the info.
