Armour trim additional applications

I feel like armour trims are a great cosmetic upgrade to armour that encourage players to explore the world but aside from cosmetics they don't have any practical use. 

What if armour trims had light status effects unique to certain aspects of the game, much like how a turtle shell is a unique piece of armour that gives you an additional 10 seconds to hold your breath under water armour trims could have unique resistances or enhancements like for instance if use the wild armour trim it would give you a slight resistance to poison.

in this way you wouldn't need to add anything new to the game however it adds further customisation for players that have practical use in the game
