I went to a McGuinness where we had a pretty strict dress code (I understand that now they wear uniforms). Boys had to wear slacks every day (no jeans) anda collared shirt -- that meant a polo or oxford style shirt. Girls could wear dressy shorts (which was unfair as we could not
), skirts, and slacks. They also had to wear 'business style' tops (not sure of the terminology). On Fridays, we could wear school spirit t-shirts.
Still, many found ways to abuse this (this was back when "grunge" was popular).
