I think it's a matter of whether your legs are not too chunky rather than how curvy you are elsewhere. I'm a 12/14 & curvy but my legs are disproportionately big so I can never get cigarette pants to fit. As long as they fit nicely - not too tight or too baggy and sit on the waist well I would have thought they'd be fine.
I got a good pair from French Connection, had to take them in at the waist to get the fit but worth it as the leg looked right. I am a size 12-14 pear shape so usually find i have to alter clothes to get them to fit
