My Catholic school is a public one...
tbh, when I first started, I didn´t think the Catholic bit was that bad. That was one of the wrongest things I ever thought.
My school pointlessly forces you to use a thin white shirt if male, or a thin blue one if female; a school tie; a dark blue blazer, even in the summer; grey trousers if male, a grey skirt (down to the knee) if female (if above the knee, the school forces the girl to wear an ankle-length one); black, grey or dark blue socks for everyone and black, leather shoes for everyone. Also, scarfs can only be used if they are blue, red and white stripes (not even in America!), jerseys can only be used if they´re dark blue, male´s hair can´t be too long or too short, and female´s hair always has to be tied back - your also not allowed to dye, use gel, highlights e.t.c. on your hair. Girls can wear one gold or silver stud on each ear for an earing, an males can´t use earings at all. Girls also can´t have any make-up. That might be all, but I´m probably missing some stuff out...
