Well apparently, even though I'm Polish, I have the body of a South African?
My waist is quite a bit smaller than my hips and I always get that gap in the back. Or, it fits my hips but cuts off circulation in my thighs.
I love, love, love Lucky Easy Rider jeans. I only get them off Ebay and I need a short inseam (5"3). With shipping, I pay less than $20.
I just bought a pair of Levis Curvy jeans from Dillard's and they fit great too although I went a size up from my usual size because they have a lot of stretch but I didn't want them tight.
I haven't gotten jeans at Gap, JCrew, Old Navy or Levis in forever. But Ann Taylor's Curvy Fit and Eddie Bauer's Blakely Fit fit me for slacks but not jeans.
I don't know why jeans are so hard to find.....
