The couple described the suggested clothing for the event as, " dive bar semiformal."

这对夫妇将婚礼的建议服描述为“潜水酒吧半正”。

This type of semiformal evening garment became prevalent in post-war fashion when the concept of the cocktail hour was especially popular.

当鸡尾酒间的概念特别流，这种半正式的晚在战后中变得流。

Mrs. Norton said the play is going to be a “semiformal occasion, ” and I know there's no way Rodrick is going to wear a tie for a middle school play.

因为诺顿太太说这个演出会安排在一个“半正式场合”，而罗德里克是断不会为了看一个中学生演的戏而大费周章去打领带的。
