Jeans dilemma

So, I know this is a completely worthless dilemma, but a dilemma nonetheless.  I have 8, count them, eight, ocho, hachi, 8 pairs of jeans for the ranch this summer.  Great.  I don't have to wash clothes but every couple of weeks.  Yep, that's right, I'm going to wear them twice before washing.  Yep, even if they're dirty, because you KNOW they're going to be dirty.  

Anyhow, the dilemma.  I have 8 pairs of jeans for the ranch.  Most of them are western, some of them are just old jeans that have become work jeans.  Some of these I have literally had since high school.  My junior year of high school.  10 years ago.  Some of these jeans are newer, you know, like circa 2002.  But of course, those are the jeans I bought when I came back from San Francisco.  One of two times in my life that I have proven I can gain excess weight.  Proof is in the jeans.  

Most...ahem...ALL of these 8 pairs of jeans are at least 5 years old, except of course the hand-me-down pair I just got.  And most of them don't fit because they are too big...or too small.  But ALL are out of style.  

Ok, so, here it is.  Do I go buy new jeans, just to get dirty and torn up, but that will fit and look nice?  Or do I just wear these super old, ill-fitting jeans?  Oh the dilemmas of working on a guest ranch.
