The sizing chart is accurate. If like me, you find yourself having to choose between your waist size and your hip size, go with your hit size. If you go with your waist size, they will still fit, but they won't totally cover your backside. They will still stay in place, but don't feel as secure as going a size up for my hip size. There is enough stretch in the material that the waist did not feel loose or slide around. When I reordered for my hip size, I was much happier with the way they felt and I could up my rating from 4 to 5 stars.
