Shirt shirt originally refers to a light woven shirt worn by adult men. /kloc-in the middle of the 0/9th century, the category of shirts appeared in women's wear, and then it gradually began to be an independent category of blouses.
It turns out that I used to use shirt to refer to men's woven shirts and shirt to refer to women's woven tops. But gradually, the word shirt no longer distinguishes between men and women, and the word blouse will also be used in some very loose men's shirt styles.
In modern fashion, there are many innovative styles improved from the past shirts and tops, but no matter how they change, they can basically be traced back to the source of styles, so as long as you remember the classic styles that have appeared in history, you can still put the novel styles in the corresponding categories.
