Garish, gawdy, with lace or staring and discordant colours: a term said to be derived from the shrine and altar of St. Audrey (an Isle of Ely saintess), which for finery exceeded all others thereabouts, so as to become proverbial; whence any fine dressed man or woman said to be all St Audrey, and by contraction, all tawdry.
