Southeast Bulloch High School Principal Trey Robertson hopes a proposed dress code will prompt a few students to reveal a little less next school year.The code, proposed only for Southeast Bulloch Middle and High schools for the 2012-13 school year, would allow students to wear polo, button-up, crew-neck or turtle-neck shirts and khaki or denim pants, shorts or skirts. Shorts or skirts would have to be no higher than 4 inches above the bended knee.Robertson told the Bulloch County school board Thursday night that teachers, parents and students participated in the process of developing the dress code proposal. The goal was to remove distractions caused by low-cut blouses and form-fitting yoga pants while not causing an undue financial burden on students and parents.The board granted initial approval to the policy.
