How to bind Armour/Clothing to Player?

What would be the simplest and least resource intensive way of binding and loading armour/clothing to a player?

The Pin behaviour is the simplest.

^ This solves the binding problem, but what about the loading part? I don't want to have 50 pieces of armour bound to the player at the same time, how would I go about setting the articles of clothing/armour and making those specific pieces bind to the player and not all of them?

Either just pin the one you want, or if they are grouped (animation frames), you'd have each group pinned and you only change the current frame to show the appropriate piece of armour. Depends how you do things.
