Hmmm. I'm 33 inch hips, 25 inch waist (on a good day - probably close to 26 inches). I find that if it fits in my hips, it's too tight in my waist; if it fits in my waist, it's a good 2-3 inches in the hips. So I'm confused, because your measurements are typical to any size chart I've ever seen.
Are you trying on different sizes? Ignoring the label, and trying a size up and a size down? Have you tried petite sizes?
When you say your waist is 26 inches, are you talking about the skinniest part of your torso, or around the belly button? For example, my skinniest part is right below my rib cage and several inches above the belly botton. At the belly button, I'm closer to 31-32 inches - and there's only about an inch between belly button and hip.
If you are trying on low-waisted jeans, you might simply be petite, or you might have a long torso.... because on low-waisted jeans the waistband falls nowhere near the true waist.
