I think that it would be very cool to have curly hairs in game, not like the sovereign one but much longer and more curly.
It would be cool to have short and long version of curly hair, like a version where the hair touches the shoulders and a slightly longer version maybe.. would love to see them similar to the 70s / 80s style ones... it could be an idea to add them maybe with an upcoming update or the next plunder pass, hope you'll add them :)
