公司白領們平時上班大都是襯衫、領帶加西褲，女士雖然花樣多一些，不過多數也都得穿正式的套裝。從西方引進的casual Friday（休閒星期五）的理念在中國也通行了好些年了，而由此興起的d wardrobe（商務休閒裝）也逐漸成為時尚界的一個熱門領域。
A third wardrobe is something that crosses the divide between Monday to Thursday and the weekend, a set of clothes with a style that lies between formal business attire and casual wear, something that’s not quite business, not quite casual, but business casual.
Third wardrobe（商務休閒裝，也直譯作第三種服裝）指風格介於工作日所穿的商務正裝和週末休閒裝之間的衣服，不是很正式，也不是很休閒，屬於商務休閒。
It is all very well turning up for work on a Friday in clothes different from those worn during the rest of the week but this has thrown up a new challenge to staff: how to feel casual but still look smart. For those who care enough, this means buying a third wardrobe.
週五上班的時候穿一身跟平時上班不太一樣的衣服是件挺好的事，但同時員工們也有了一個問題：怎麼穿才能顯得比較休閒但看上去還比較正式呢？對於那些講究細節的人來說，解決的辦法就是買一些商務休閒裝。The 800-meter-wide (half-mile-wide) Victoria Crater in the Meridiani Planum region of Mars, photographed by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter, is seen on July 18, 2009.
