Used, but in good shape.
No holes, tears, patches, frayed areas, stains, ripped seams, etc.
If someone gave your child that item to wear, would you feel okay sending him or her to school in it, knowing it would reflect on you as a parent? If so, it's gently worn. If you would only let your child go out to play in it, not caring if it got ripped or stained, then it's not.
