I have a very big difference in my waist/hip ratio...I am also a pear shape. Unfortunately, relaxed fit jeans...and even the new Lee Curvy Fit (that say fuller hips/gaps happen at the waist, etc.) on the tag don't fit me!!!!
What I HAVE found that fits me is a small brand of designer jeans started by a woman with the same fitting problem. The brand of jeans is called Little In The Middle. (

They actually make the jeans a FULL SIZE SMALLER in the waist, than they do in the hips. Basically, you order the jeans based on waist size, and the hips are "one size up". So, a pair of their jeans in a 12.1 are a 12 waist/14 hip. A pair of 8.1's are an 8 waist/10 hip...a 14.1 is a 14 waist/16 hip.
They are FABULOUS. They have them in low rise and mid rise...and many different colors and styles. They are usually boot cut, because that balances out fuller hips. They come in a 34" inseam...so if you are average or petite, you just pay a few bucks at the local alterations place to have them hemmed.
I cannot say enough about them...for the first time EVER I don't have to cinch my pants up like a paper bag with a belt. My measurements currently are an 8/10 through the chest, based on designer/store brand...and a 10/12 hip based on the same thing...I am always a size larger in the hips on size charts. Little In The Middle has solved my fitting issues!!!
