Are women's jeans 180 yuan expensive?

No, 180 yuan jeans are in the middle price range.

Not too expensive and not too cheap. The quality is ok. But not as good as those famous brands. At least 180 yuan's jeans will be better than jeans of several tens of yuan in terms of fabric and wearing comfort. So it is still worth buying. After all, it's worth it. It depends mainly on your own economic situation.
