If the cap fits,wear it.
    Definition: if the statement about someone is true, then one must accept it.
    這個(gè)習(xí)慣用語中的cap也可以是shoe或者h(yuǎn)at, 一般來說，If the hat/shoe fits，wear it主要是美語。而且，這個(gè)慣用語可以直接簡單地說成If the cap/hat/shoe fits.它的意思是如果所說的話符合你的情況，你就應(yīng)該接受或者承認(rèn)。這里的statement通常是不太令人愉快的, 如：意見、批評(píng)或懲罰等。如果某個(gè)人因所作的事感到愧疚卻又不肯承認(rèn)或接受，你就可以用這句短語了：Look, I didn't say who was to blame for this mess, but if the cap fits, wear it. 又如校長開會(huì)時(shí)絕對(duì)可能嚴(yán)肅地說：I have noticed that there are some classrooms where the pupils have been in at least five minutes before their teacher appears. I will name no names but, if the cap fits, wear it.
