Most Helpful Girl
My favorite pair of jeans was ironically $20 (great quality, really comfortable, and they've last forever in great shape). Usually I try to stick to $50 or under, but when I really want to pay for quality I have no problem dropping $89-100. But anything beyond that is just too much for me for one pair of jeans.
Most of the girls I know of though tend to spend at minimum $100 and anywhere up to $400 or 500; which I think is definitely a bit too far. One of my best friends loves to shop at thrift stores and usually spends $10-15 dollars on jeans and as far as I can tell, they always look great on her and seem pretty comfortable. I guess it's just dependent on the individual.
