Hey, I have a huge interest in clothes but I don't get why people spend hundreds of pounds on jeans, when any good shop will have a pair that fit and look decent.

I once when I was younger ignorantly bought some £210 jeans from a charity shop for £5, and they lasted a lot shorter than any other pair of jeans I bought, and tattered surprisingly quickly, (I also wonder about people who by plainest clothes for fashion labels)

what's the difference between fashion jeans and normal jeans?
