Tarlton,
Trying to get the right size when you order a new product for the first time can be frustrating. You probably require at least a size Medium in the Gary Hi-Back No-wick PUL pants. In addition to accommodating your waist size, you must allow for the bulk of the cloth diaper. Rather than a "fit," you need a "loose fit."
I use night-weight pre-folds with two thick booster pads and needed to go up a size larger than the charts indicated to allow more space for the bulk of the diaper. When I first received the PUL pants I thought they looked way too large, but they fit perfectly and no more leaks.

Good luck.
