Gild the lily
Meaning
To apply unnecessary ornament - to over embellish.
Origin
Shakespeare didn't coin the term 'gild the lily', but he came as close to doing so in King John, 1595:
Definition:
To adorn unnecessarily something already beautiful. The expression is a condensation of Shakespeare's metaphor in King John: "To gild refined gold, to paint the lily ... is wasteful and ridiculous excess." i.e., you wouldn't need to add gold to a beautiful lily.
Etymology:
Idiom: gild the lily1. To adorn unnecessarily something already beautiful.
2. To make superfluous additions to what is already complete.
[Middle English gilden, from Old English gyldan; see ghel-2 in Indo-European roots.]
