Lengths are different!
I love these pants in how soft and comfortable they are. Easy to move around in. Love the color choices. I am 5'5 130 pounds and got the 6P. They fit snug at first, but they will stretch out! The length is perfect 30" on the firma and navy colors, but for whatever reason the retro khaki is 1-2" longer!! I ordered 3 pairs of the retro khaki thinking there was some mistake, but all were longer and had to be sent back!
