I bought a pair of new jeans (511 skinny by levi's). Initially I bought a size 30 but then I decided to exchange them for a smaller size 29 since they were a little loose around my thigh and leg area.    So I get home, try on the jeans and they fit nicely around the waist, thigh, and leg area.. but one problem. I find that the jean folds into the gap between my buttocks, which kind of looks like I'm giving myself a wedgie. I'm wearing the jeans as low as I can, below...
