From the PRD:
When an article of magic clothing or jewelry is discovered, most of the time size shouldn't be an issue. Many magic garments are made to be easily adjustable, or they adjust themselves magically to the wearer. Size should not keep characters of various kinds from using magic items.
And then it also gives chances of getting various sizes of armor and weapons…
What should I take from this? Do all magic items resize appropriately, or is it only wearable stuff?
Assuming there's no official/RAW answer, what are suggestions to this issue, knowing that I'd rather have such loot be used rather than sold.
