A useful new skill would be Tailoring. One with tailoring would be able to make clothing only accessible to those who have previously tailored it (which would translate to 'Free once tailored' items in the wardrobe). There might/would be a new tool, potentially a new skill chain (Tailoring I, II...), and so forth. I'm not sure paper would quite cut it, so there might be some new resources to consider. I'd say a sewing kit with durability, thread to make/find/buy, things to that effect. Random thoughts~
