I got a pair in Gap yesterday, and I'm very pleased with them. Three leg lengths, two colours of denim - £45. They are the right height at the waist, and I'm a size 14 and the 30" waist is a perfect fit. Just called Straight Leg I think
I wear levi demi curve too and just got a straight leg pair for summer. They are a perfect fit for me. I find boden an odd shape over the hips, just not quite right and as for Gap the waist is always massive compared to the fit on the thighs so no good if you are hourglass type shape.
