The Right Jeans

Is it possible to get jeans that fit, or is that just a media myth?  If you're on a budget like I am, and you don't have an infinite amount of money to spend where ever and on what ever you desire, can you really find a pair of jeans that fit?  The ads on TV, on-line, and in fliers and magazines make the answer to my question appear to be positive, but I don't think so.  I recently picked out a new pair of jeans while shopping for groceries (which tells you, again, of my small budget), and thought I had hit the jackpot.  The tag on the front showed a younger woman in the same style, with a belt, a nice blouse, and some boots.  Well, in the fitting room at the store, I didn't have what was needed to complete that image, so I bought the jeans on faith, that with the right combo, they'll look good at home.  Okay, I'm home.  What's wrong with this picture?  Even with one of my better blouses, a good belt, and my favorite boots, I still look like I'm wearing the dreaded MOM JEANS.  Ugh!  All I wanted was some jeans that won't show my underwear every time I sit down (or worse).  I also get tired of constantly yanking on the waist to pull up my jeans that, for some reason, want to creep the other way.  Why is that?  I know they're the right size; I don't get it.  I don't have an ending for this post.  Any suggestions?

This one is called, "Pair of Hearts", chosen because I've often wondered why pants, of any kind, are referred to as "pairs".
