Hi, have begun to feel frumpy in my boot cuts, would like some straighter cut but really dark denim jeans for spring. Would like a lightweight denim in a really dark blue with a bit of stretch in it. Saw some nice Great Plains ones in a local shop (in size 8 ) but they are not on the website. The Boden ones look OK but not sure. I'm 5'8" and a size 14 bottom half (but getting smaller!)
