Other forms: fineries
Finery is showy clothes and ornaments worn for display. Dressed in her finery, wedding finery, all their finery.
It is faintly mocking — finery suggests display for its own sake, where fine clothes need not. It is uncountable and usually possessive: your finery, their finery. Note fine beneath it, plus the -ery ending that makes collective nouns.
