so i tried many iterations of this 6 in total i wanted to make the jumper thick and puffy and warm looking but vam does not do thick well so i had to go with texture/normal's to create an illusion of thickness.
that said i do quite like it there is a puffy coat looking version and a few librarian old school style patterns and as always a diy white to allow for customization.
