Some schools have unisex uniforms—most often a distinctive shirt, and sometimes pants of a given color. They may also require that a specially-designated, more formal uniform be worn on liturgy days or other special occasions. Uniforms may vary based on time of year. At many schools, students are excused from having to wear the fairly formal (and warm) uniforms described above during the hotter months of the school year in favor of lighter uniform clothing such as skorts, skirts, or shorts worn with knee socks, crew socks, quarter socks, or triple roll socks, or capri leggings under the skirt. Capri pants are also allowed in some schools. However, at some schools appearance and formality prevail over comfort and students must suffer through the warm weather in their full uniform, which can include long-sleeved dress shirts, ties, wool sweaters, blazers, wool skirts, jumpers, leggings and tights. In many schools ballet flats for girls and Sperry Top-Siders for both girls and boys have become popular and acceptable footwear with the uniforms. Scrunchies, headbands or headwrap style headbands are usually worn in school colors and patterns.
