I'm a thin rectangle so I usually find that pants are too small in the waist if they fit in the hips and thighs. I look for pants that give me some shape.
Modern boot cuts pants: The cut is great on my shape. They're fairly slim in the hips and thighs, then a nice bootcut at the bottom. I really like the back flap pocket which gives some detail without being bulky. I have to say they're one of the best pants I've found for flattering my (somewhat flat) backside! The fabric is nice also- a polyester, viscose, spandex blend. I think they'll wear well and won't wrinkle.
Perfect trouser pants: These didn't work as well for me. When the waist fit, the hips were too big (typical problem for me). The fabric and cut was nice though and I was disappointed they didn't fit. I think these would be perfect for an hourglass.
