Yay, at my daughter's school their uniforms are color coded according to grade level. The kindergarteners wear navy blue polos, in what my daughter wears. The HS section of my daughter's school wears a "Catholic school" type uniform. My son's school only two colors...gold or brown, the elementary grade kids wears the gold polos and the middle schoolers wears the brown polos. And everyone wears appropriate khakis.
