And don’t despair -- there are modest alternatives. Some readers recommended Lands’ End and L.L. Bean, both of which feature one-piece suits and “tankinis.” In my book, Home Invasion, I list two others: Modest Apparel USA (“an alternative to the promiscuous fashions that are prevalent in clothing stores today”) and Modest By Design (“clothing your father would approve of”). There are many others. As one reader said, “If you Google ‘modest swimsuits,’ you’ll find literally thousands of options.”

Still, even with an array of options, it can be tough to take a stand in favor of modest clothing. But it can be done. Just ask some of the friends Kristin has brought to our house.

Occasionally, a girl visits wearing something inappropriate -- a midriff-baring shirt, a short skirt, a low neckline.

I smile and say, “God made you a person of value. You’re somebody special who deserves to be respected. So when you’re in my home, I want you to dress in a way that reflects the treasure you are. So let’s go upstairs. You can pick out anything you like to cover up while you’re here.” There may be a gasp -- often, nobody’s ever told them that their body is a treasure to be respected. But then they get it. And you know what? A bond is created, and they appreciate what I’m doing.

Women and girls who decide to dress modestly often have another surprise in store -- men and boys treat them differently. In the book “Dressing with Dignity,” former model Colleen Hammond explains why:

“I believe it is because, subconsciously, men can read women’s body language. If they see a woman who dresses with dignity and carries herself with grace and femininity, they pick up on that. They take it as a sign to approach her with the respect, reverence and honor a woman ought to have.”

Exactly. And if a girl dresses like a streetwalker, they pick up the opposite message. Is that the signal we want our daughters to send?

I’ll close with something Muhammad Ali’s daughter says her father told her:

“Where do you find diamonds? Deep down in the ground, covered and protected. Where do you find pearls? Deep down at the bottom of the ocean, covered up and protected in a beautiful shell. … Your body is sacred. You’re far more precious than diamonds and pearls, and you should be covered, too.”

So hang in there. You’ll be glad you did.
