Trying to recall a Gilbert & Sullivan quote: "remains of a fine woman"--?

In the spoken dialogue of one of the Gilbert and Sullivan operas, the older female character is described as having the ruins or remains of a fine woman about her.

An older woman who is the butt of jokes for having lost her youthful figure is a staple G&S character, so I am not coming up with any hook that helps me remember which one this is. I’d like to find the exact quote.
