gild the lily, to

To add excessive ornament; to pile excess on excess. This term is a condensation of Shakespeare’s statement in King John (4.2), “To gild refined gold, to paint the lily . . . is wasteful and ridiculous excess.” Earlier (sixteenth-century) versions of this idea cited whitening ivory with ink (Erasmus, Adagia) and painting fine marble (George Pettie, Petite Pal- lace). Byron quoted Shakespeare correctly (“But Shakespeare also says, ’tis very silly to gild refined gold, or paint the lily”), in Don Juan (1818), but sometime during the succeeding years it became the cliché we now know.
