The tone is sharp and , stronger than a quiet word and a little more set-piece than just “she shouted at him.” It is slightly old-fashioned and a bit British-flavoured — you meet it in stories and news more than in the chat of young people, who might say a telling-off instead.
The tone is sharp and shaming語氣尖銳又帶羞辱， stronger than a quiet word比小聲提醒還重， and a little more set-piece than just "she shouted at him."也比單純「她對他大吼」更有套路一點。 It is slightly old-fashioned and a bit British-flavoured這個說法有點過時，也帶點英式味道—— you meet it in stories and news比較常出現在故事和新聞裡 more than in the chat of young people比年輕人聊天時常見， who might say a telling-off instead他們可能會改說telling-off。
Though actually, it has nothing to do with clothes. (Dress-down Friday, when offices allow casual clothes, is a different phrase.) Informal to neutral, a little dated.
Though actually不過其實， it has nothing to do with clothes它跟衣服一點關係都沒有。 (Dress-down Friday, when offices allow casual clothes, is a different phrase.)（Dress-down Friday，也就是公司允許穿便服的星期五，是不同的說法） Informal to neutral, a little dated語體上偏口語到中性，用法有點過時。
