The Gap ones everyone loves are too low rise for me so I had to go on a quest to find my own perfect pair. I'm crazy about these:

I was terrified when I first opened the package because they looked so TINY and I did have to squeeze my way into them somewhat, but within minutes they molded to my body and have been perfect ever since. If you are tall you might like the inseam as well (I had to hem mine, of course). I have worn them a few times between washes and they never bag out and are always nice and soft. Might be worth a try if you are long in the rise, as I am.
