Loungewear is soft, comfortable clothing you wear when you are at home and not going out to work — things like loose trousers, a hoodie, a matching set you can sit around in. Shops use it as a name for a kind of clothes: not pyjamas exactly, and not sports kit, but clothes that look tidy enough for the sofa, a video call, or popping out for milk. You put loungewear on when you want to feel at ease. Though actually, companies stretch the word a lot. Some ‘loungewear’ is just ordinary casual clothes with a nicer label, and some of it is smart enough that people wear it outside. It is a fairly new shopping word, informal, and you meet it on labels, in adverts, and in magazines more than in old books. It does not mean clothes you wear only in a hotel lounge. It means clothes for a slow, at-home kind of day.

居家服、居家休閒服（不是直譯「客廳穿的衣服」；店家常用這個字指可在家放鬆、有時也能出門的套裝）
