Another thing you could do, is create common events for each change of armour. Each common event will have all the prgramming needed --> change sprite, change face etc. <-- in it, so you won't have to mess around with long codes for every time you change armour.
I don't know how you are changing the armour etc, whether you use only four sets of armour, and a choice menu or what, so the above can only really help if you have programmed it.
