Upperwear is the wardrobe you create when you work on line or on TV and are only 'seen' from the waist up.
“上装”就是在网上或电视台做直播节目等工作时,观众可见的腰部以上的服装。
Example:
During video calls and meetings she wore professional looking upperwear, such as blazers with pearls, while at the same wearing jogging pants.
在视频通话和会议时,她会穿职业的上装,比如小西服搭配珍珠首饰,而下半身一般穿的是运动长裤。
