Hanfu movement (汉服运动 / 漢服運動), or the Hanfu subculture, is a 21st-century movement that developed in China; its advocates want to reintroduce the wearing of hanfu for all Chinese in daily life as a way to stress values and support unity. This term encompasses the historical clothing styles worn by the Han Chinese before the Qing dynasty (1644–1912). While the Han Chinese comprise the largest ethnic group in China, there are 55 other ethnicities with their own traditions.
i think the best ones are the ones back in Jing Yong Era. those clothes swordsman & women wear. Abit like Japanese Samura clothes but neater & nicer.
Hanfu, i think unless you are Leslie Cheung, won't look nice. And these type of clothes really need to match with long hair, for women maybe suitable, for men, really out of place the modern hairstyle with ancient clothes.
