It's not what you're thinking, mothers of tween and teen girls.
I'm talking about the t-shirts with sayings on them. The ones that proclaim, "Cute how you think I'm listening" or "Don't give me any attitude; I have plenty of my own!" Think seriously about the kids wearing these fashion "statements."
The child with major attitude problems, the one who misbehaves more often than not, does not need to wear "I have issues" or "Be glad you're not my parents" plastered across his chest. The poster child for the IEP box that says Behavior impedes child's learning or that of others should not arrive at school sporting "Selective Listener" on his sweatshirt.
Be logical. Imagine walking into a meeting with your boss and flashing a designer tee that says, "I see your lips moving but all I hear is blah, blah, blah, blah, blah." Just how would that be perceived?
When I taught the fashionistas of 6th grade, the dress code technique called for turning offensive shirts inside out. If the student wore the same shirt again, s/he would have to call parents for an alternative or wear a "spare" from the office stock. This applied to shirts with alcohol or drug references, offensive language, or other obvious idiocies. The clueless sayings, however, are a gray area. Maybe they're funny when an honor student wears them; maybe not. In my classes, I see them more often on the kids who exhibit the very problems silkscreened on their wardrobes. When I'm issuing a detention to a kid for disrespect, I don't want to look at her and see the little rabbit quoting "Lalalalalala I can't hear you!"
After a certain point, our teens and 20-somethings choose and buy their own clothes. Until then, we are parents; hear us roar! Hear our wallets and our logic and sensibilities. Don't make your kids stand out for the wrong reason. If they're under your roof, living on your budget, you still have some semblance of control. Use it.
