But if we want to summarize the similarities between men's wear and women's wear, I think men's wear and women's wear can be worn together if they are neutral. Neutral clothing has several obvious characteristics, one of which is relatively loose. Because there is still a certain height gap between boys and girls, girls should wear boys' clothes, and the clothes need to be loose, so that both of them can wear them. If boys want to wear girls' clothes, it's the same. Unless boys are short, they must wear women's clothes in a large size. So from the size point of view, I think women's wear with larger size is qualified as men's wear, and boys can also wear it.
On the other hand, color. All the colors suitable for girls are pink, and if they are pink, they are not suitable for boys. Because girls are still more delicate than boys on the whole, many colors are beyond the control of boys. If women's wear is regarded as men's wear, it should be dominated by cool colors such as black and gray. Because the two colors of black and gray are actually worn by boys, if women's clothes are to be regarded as men's clothes, they should not be too pink in color selection, but they still need a sense of stability and maturity.
Therefore, combining the above two points, women's wear in gray, black and cool colors can be regarded as men's wear. The style should be looser.
