In Colombia, all students are required to wear uniforms in both public and private schools. Uniforms in Colombia consist of two sets; one for everyday use and one for physical education. Everyday use uniforms for girls generally include a knee-length skirt, a white t-shirt with a vest, and long white mid-calf socks. Boys typically wear long dark pants and a long or short-sleeved shirt. The shirt usually has the school's symbol on the left side. The sports uniform consists of sweatpants, a collared t-shirt, and white sports shoes. The designs and the colors of the uniforms depend on the school's colors and the principal's preference.
In Spain, uniforms are not mandatory in public schools unless the school council votes to require uniforms. Although uniforms are not mandatory in public schools, most private schools require their students to wear uniforms. A typical girls' uniform consists of a shirt and jersey skirt, while boys wear pants and a white t-shirt with a jacket.
