I agree with Lewis, and not "helpful" Hattie.
My size 5 sister, with legs she describes as, "chicken legs" (read: very slender legs), has thighs that rub. It can happen to anyone, big or small.
In any case, I like the recommendation to try to prevent through the satin patch: who knows? It might (maybe) still work after the fact? There is also a website about what is called, "Denim Therapy." They charge $7 an inch, and I think $12 to ship your jeans back. They match the right color, fading, texture, etc. to your jeans. You could check it out if you want.
Otherwise, I have found that buying from certain retailers versus others makes all the difference in the world between jeans that last, and ones that don't. I like to go to Lane Bryant for many of my clothes. I still have items from a shopping trip I made about 5 years ago that haven't faded, torn, become threadbare, pilled, or anything...even after 2 years touring with only about a week's worth of clothes to wear, washing them every week! When I went to one famous everything-in-one-store retailer, I had to throw out the pants after a whopping 2 months! Certainly not worth $20.
One of the manufacturers for Lane Bryant is called Venezia Jeans. They make many things besides jeans, and I think they manufacture in standard sizes as well, if you are a standard size. They can be a little pricy (not terribly so), sometimes, but being able to keep my classic-style clothes over five years has more than paid for that $200 shopping spree. I think the price was more than worth it.
that's my 2 cents, for what it's worth. Good luck with your repairs!
