答案

帽子的尺寸
帽子的尺寸是通过测量人耳朵以上1/2英寸（1.3厘米）处的头部周长,除以圆周率π决定的.在英国,一顶合适尺寸的帽子比在美国要小1/8英寸左右.帽子的尺寸以厘米或者英寸计量取决于生产它的制造商.（昂贵的）呢帽可以根据需要适度拉伸,而便宜的帽子常常是标准尺码的,分为小号、中号、大号.有些帽子尺寸可以调节,比如棒球帽.
帽子的组成
一顶帽子包括四个部分：
帽冠——帽子中包覆着头的部分.
帽沿——从帽顶后端水平伸出并绕帽子一周的坚固金属支撑.
帽舌——（英国称“Peak”,美国称“Visor”,又叫“Bill”）帽子前端的坚固支撑物,用来挡雨或者遮阴.
遮阳布、吸汗带或者帽带——帽子后部放置的布带或者布片.吸汗带通常设置在帽子里面与皮肤直接接触,并且可以通过顶部的绳子进行调节,而遮阳布和帽带设置在帽子外部.各种军帽,比如澳大利亚的宽边软帽和太阳帽,都将帽带当做遮阳布来使用.
