I simply cannot find a pair of jeans that fit! I have tried numerous brands and types, high waist, mid rise waist, skinny, bootcut, skinny bootcut, and they all look fine when I first put them on. But then, when I walk, or move around a little, they all start to slide, creating a muffin top, and then when I bend over or sit, you can see my bottom (this has put me in some embarrassing situations

since I have a young DD and I have to end over a lot). I don't like the look of belts, and I am uncomfortable in jeans that don't have a little stretch, so I don't know what to do. I never used to have this problem with jeans, and I am not sure how they are different now, but none of them fit me. I am somewhat tall and have an hourglass figure (small waist and rounder hips and butt). I usually wear about a Size 10 in jeans. Any suggestions.
