I think it would be pretty useful to be able to try on different wearables with our current outfit before buying them. Maybe something like a separate paper doll we can open that allows us to target any piece of clothing/armor, even if not in our inventory, and equip it onto the second paper doll which would be temporary. This is a lot more useful than looking at other peoples' paper dolls since we would be able to try things on with our current outfit or make a completely different one.
