Based on my experience, there's no quick and easy way, unfortunately. I'm genetically programmed to be pear-shaped, and when I lost weight I just became a smaller pear.
But, I was able to take 5 plus inches off of my hips over time (over a year) by losing weight overall (40 lbs) and following a balanced workout routine of cardio and strength / core conditioning. It just takes time and persistance. I think that strength training is really key -- it firms and tones up the lower body while building up the upper body can help to visually balance out the lower half. So ... just keep plugging .... it happens gradually, but it does happen if you stick with it.
