I've seen much worse than a t-shirt dress and a head scarf. In elementary school, I had a classmate whose mom was a stripper and many times would pick him up after school dressed for work. Now in that case, I wouldn't mind a parental dress code if only to spare the student from humiliation. But otherwise, I think its a bit ridiculous to have a parental dress code.
