Welcome to Fool Moon Kandy.

Actually, what I'm seeing more and more here in what the kids are wearing, are not "sexy". Here, Tripp pants are in style. They're very loose fitting, not tight at all. There's also Trip shorts.
My adolescent daughter likes t-shirts, mainly music groups and singers. Most of her friends are the same. When she got a bathing suit for this year, she picked out a pretty conservative one piece suit.
What is "sexy" for a pre-teen? Wouldn't one have to look at it with each outfit? When I was growing up in the late 60's and into the 70's mid riff outfits were popular with women and girls. I see pics of myself wearing these outfits and they weren't sexy at all.
What's wrong with Style magazine? I read magazines like that when I was growing up and I didn't dress "sexy" or inappropriately in school. Nor do I now. It's part of growing up and trying to find oneself.
With two of my three kids in their adolescence, I don't see such a bleak future, Kandy. My children are kind, caring, non-violent, polite, etc. And none of them have ever read any part of the Bible. Parenting is the issue, not religion. Good parenting generally produces good kids.
I find our public school here very lacking in many ways and see a lot of problems with it. But none have to do with religion, God or the Bible.
