ZARA is the biggest seller in the world. At H&; Time ZARA's boss is also the richest man in the clothing industry. More bosses than LV and Dior. (But their total wealth is not much different. )H &； M is the first in Europe, but HM is more famous than ZARA in China. As for the world's number one clothing manufacturer, I don't know what you mean by sales. Anyway, the number one seller in the world is ZARA.
