I wonder how quickly our children could point out examples of immodesty *outside* of dress. I wonder how many of us wear very conservative clothes to church, but go home to our immodest homes. Or how many of us wear modest clothing to the grocery store, but then go and have very immodest conversations with our friends.
I think to define modesty strictly by how much skin we're showing or where our hemline is to really really miss an opportunity to assess where we are spiritually and what kind of humility we're expressing and make some changes.
