I have unusual proportions. My hips and legs are large, but my waist is small. It's pretty much impossible to wear anything off the rack which is why I ordered custom jeans.
I ordered baggy style jeans to try and make sure they didn't constrict my knees and lower legs. You don't need to do this - the bagginess is added on top of your measurements, and they do match your measurements exactly. I couldn't be happier. Most comfortable pants I've worn in years. All the jeans in stores seem to be designed for frogs - huge waist, itty bitty legs.
