Now you know the root of the old saying about putting lipstick on a pig -- you can dress it up however you want, but it's still just a pig. Of course, if you love bacon, that may be good news indeed, but I highly doubt the Old Testament was looking at things from that angle, seeing as how they didn't eat pork...
But the Proverbs here are reminding us that anyone (not just women) who fails to exercise discretion is hoping that some physical traits will cover up a lack of character. And this can work for a while... but eventually, character is always revealed. Who we are matters, and Proverbs is advising us to build strong character, for that's more important than superficial traits like beauty. It's a hard thing to teach children, and to believe for ourselves, because we see how those with strong superficial traits can get ahead -- but character matters more. May we pursue sinking our roots deep into Scripture and drawing wisdom from that, to pursue Godliness above all else, to grow closer to God, no matter how tempting and alluring some of the world's treasures are.
