I am a size 16 long with big hips and a small waist.  I have always liked the way bootcut jeans (515s) make me look, but the standard dropped waist is uncomfortable and constantly gaps at the back, even when I wear a belt.  These jeans fix that problem completely!  The waistline curves up so that it is at my natural waist in the back, but still looks a little dropped in the front.  They fit perfectly too!
