The act of fastening or securing with garters; also, garters collectively or the material used to make garters.
From garter plus the gerund suffix -ing. Garter itself comes from Old French gartier, possibly related to garet (leg bend). The -ing form indicates both the action and the object itself, a common pattern in English.
