DS8 has some t-shirts from his gifted school and various gifted programs. I am kind of selective about where he wears them. For example, I wouldn't encourage him to wear them at big family functions, because I don't think his cousins are in GT programs and that would be awkward. Regular day-to-day stuff, I wouldn't think twice about him wearing them. Of course, they don't say things like, "I am smarter than you" on them. They just list the school or the program and most of them have bright and colorful designs on them.
