I am 5'5" and about 125 lbs. I ordered a size 2 and they fit well and are flattering and comfortable. I use them as light-weight travel pants. They do not wrinkle and can be washed and dried in a hotel room. The lightweight material makes them quick drying and cool to wear in the tropics. The slightly stretchy material makes them flattering and comfortable. The pockets are zippered and so good for keeping money and small items. Putting larger items in the pockets makes them bulge and spoils the silhouette. The pocket on the leg is very useful for things like cards and keys. The pants are well made and even after wearing them heavily for several months there is no sign of a seam failing.
