Go for jeans with Lycra in, at least 4%, that way the waists stretch too.
I find I can't wear branded jeans, as they seem to be made for bumless, thighless anorexics. I've always liked jeans from H&M, they usually have stretch in and the rises are not so low, that your pubes or bum cleft are left uncovered. H&M jeans retail at about �30.
I also like Uniqlo jeans, they have many different cuts, from skinny, relaxed fit and bootcut and the cut is quite generous too, prices are reasonable, about �25. Other than that, Gap jeans can be quite good, but pricey at �50 or more.
