What Hanfu should I wear at 20 degrees?

At 20 degrees, it's not too cold. You can wear clothes made by Song Dynasty, pleated skirts and clothes wiped by Song Dynasty. You can also wear Amin's big dress, and you can wear Boming's big dress in this weather. It is also a good choice to wear a chest-length skirt and a large sleeve shirt outside. Of course, you can also choose to mix and match, such as shirts with horse-face skirts and short skirts with skirts.
