Stuff like tattoos, skins for horses and ravens should show a preview on Eivor and the pet companions when we hover mouse on the item icon. Settlement cosmetics can just show an enlarged view of same. Armors and weapons could either show Eivor equipping same in a side preview panel.
AAA rated game should be able to have these basic features. Surprisingly, I see them missing even in other major titles like Cyberpunk (no preview of clothes you can purchase). Not sure if it is really much harder to implement in code, than it sounds.
