Well, this is the generation that has grown up... yourself, what, read the story for the beginning. Previously, dress was called any, in general, any clothes, except the upper and lower. And a jacket with pants, too. It was after the dress began to be called a detail of the female wardrobe in its modern form, and to men's clothes this word ceased to relate. I am ashamed of not knowing this!
