This verges on necroposting, so I apologize, but I'm oh-so familiar with the woes of having no hips and long legs.
It's a splurge, but I've had a lot of luck lately with Levi's and Gap. The stores almost never have anything in tall sizes, but (depending on where you are) they can just ship them...most of these places go up to a 36 inseam, and a size sixteen; I'd recommend straight-cut especially for someone with that sort of build. I hope this is at least a little bit helpful; I know these are "younger" stores, and way overpriced, but I've had a lot of luck with them in the past.
