G-star and Calvin Klein jeans which grade is higher?

My classmate went to the United States for a trip

The CKJ jeans over there are 30~50 US dollars

He bought a pair of CKJ pants for 30 US dollars

And the GS pants are at least 100 US dollars over there!

So there's a price difference between CKJ and G-STAR overseas

But in China, the price is about the same for both brands

Because GS is cheaper in China, after all, it's processed in China

And I can't tell you why CKJ, which is also processed in China, is still so expensive!
