Vintage clothing is a generic term for new or second hand garments originating from a previous era. The phrase is also used in connection with a retail outlet, e.g. "vintage clothing store." It can also be used as an adjective: "This dress is vintage."
The word vintage is copied from its use in wine terminology, as a more elegant-seeming euphemism for "old" clothes.
