Well, since "armor" is just a very specific barrier, I would handle it like that.
So a force 4 spirit possessing clothing would add 4 points of armor for everybody wearing this shirt. (Rules for barriers: Shooting through a barrier. The guy defending only gets HALF the armor)
(And this is actually, much too good! It would assume that the shirt covers the whole body. Which is silly. So I probably would adjust for that two and half it again if it only covers half the body.)

Depends on the GM. If you can just have force 4 spirits possess your stuff, for +8 points of armor each.... Even if it would not count as hardend...
Just saying magical underware+magical T-shirt for 32 points of armor...
And services of force 4 spirits are quite cheap... (Or make it with force 3...)
The trouble with this is that I would let the spirits take damage, too. Without hit locations, simply every spirit posessing a piece of clothing will take the attack in addition to the person wearing the armour. So an F3 spirit being hit by a 7P attack will start taking damage. In addition, while there are no rules for armour degradation, there are rules for posessed stuff taking damage, and if the posessed piece of armour gets "killed", then I would have the armour get destroyed as well.
Personally, I would ask the player to tone it down: Max 1 spirit in armour, and it has to be a piece that covers the entire body. Posession is still worse than materialization where versatility is concerned, but it does make for one hell of a tank mage.
If you really want to screw with a player you have to question what kind of service is used in order to posess a piece of armour. The posession itself is not a service. For how long will that service last?
Then, does the armour now become mobile? The spirit might be able to walk a pair of pants around town. If so, then actually it should encumber more, because the spirit has to predict the wearer's movement and move the armour.
Unfortunately, I'm thinking this is really a gigantic oversight in the rules. It SHOULD be possible to stack layers of spirits, but it's obviously quite catastrophic from a balance perspective.
