A foldable garment hanger is disclosed which includes a hook which can be folded relative to the garment supporting portion by virtue of a hinge. A size marker is attached to a connecting portion which joins the hook to the garment support portion and includes the hinge. When the size marker straddles the hinge the connecting portion is held rigid thereby fixing the hook relative to the garment support portion. Preferably the size marker is slidable to expose the hinge thereby allowing the hanger to be easily moved between an erect display condition and a folded transportation condition.
