Size 0 Petite Dresses Where Can I Find Small, Petite-sized Dress Pants That Look Good?

Where can I find small, petite-sized dress pants that look good? - size 0 petite dresses

I bought size 0 short in the Express, but these are too big in the butt and thighs! I have even a little chubby thighs, so I do not understand. It should not be that hard. I used to have the pants in the Limited, but disappeared.

Where do you buy your pants when you are small and short 5'3 (ish) like me?
