I didn't say it was the same. I said it was immodest. I stand by my opinion. The only schools my son is applying to either have dress codes or uniforms to prohibit that sort of thing, and my daughters won't be dressing that way, either.
Unless you're male, you can't appreciate how distracting that is. And, unless you're a parent, you can't appreciate wanting to protect your children from it. The number of fathers of teenage daughters who honestly think it's a great thing for their daughters to go to school with their bellies hanging out is pretty small, IMO.
