冠冠 古代贵族男子所戴的帽子。古礼，贵族男子年二十而加冠，举行“冠礼”。但古代的冠，只是加在发髻上的一个罩子，很小，并不覆盖整个头顶，其样式和用途同后世的帽子大不相同。《说文》：“冠，絭也，所以絭发。”（絭，束缚）古人蓄长发，用发笄（簪子）绾（系，盘结）发髻（挽束在头顶上的头发），然后再用冠束住。上古的冠，只有冠梁。冠梁不很宽，有褶子，两端连在冠圈上，戴起来象个罩子一样，从前到后，罩在发髻上。可见，那时的冠，并不象后来的帽子那样把头顶全部盖住。冠圈的两旁有两根小丝带，叫“缨”，可以在颔下打结。《史记·滑稽列传》：“淳于髡仰天大笑，冠缨索绝。”古代的冠，种类较多，质料和颜色也不尽相同。秦、汉以后，冠梁逐渐加宽，同冠以圈连成覆杯的样子，冠的名目和形制也日益复杂。古代的“冠染”，呵根据梁数的多寡来区别官阶的高低。例如唐代品官服制，一至三品戴三梁冠，四、五品戴两梁冠，六至九戴一梁冠。宋代贵族妇女也戴冠，例如安阳宋韩琦墓出土的金丝编织的花冠，制作工细，与故宫旧藏的《历代帝后图》中宋代皇后所戴的凤冠极为相似。
