公司白领们平时上班大都是衬衫、领带加西裤，女士虽然花样多一些，不过多数也都得穿正式的套装。从西方引进的casual Friday（休闲星期五）的理念在中国也通行了好些年了，而由此兴起的third wardrobe（商务休闲装）也逐渐成为时尚界的一个热门领域。

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 attire² and casual¹ wear, something that's not quite business, not quite casual, but business casual.

Third wardrobe（商务休闲装，也直译作第三种服装）指风格介于工作日所穿的商务正装和周末休闲装之间的衣服，不是很正式，也不是很休闲，属于商务休闲。

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.

周五上班的时候穿一身跟平时上班不太一样的衣服是件挺好的事，但同时员工们也有了一个问题：怎么穿才能显得比较休闲但看上去还比较正式呢？对于那些讲究细节的人来说，解决的办法就是买一些商务休闲装。
