I ordered a 12 x 30 and what I received was labeled as such but in reality had a 31.5 inch length.  Additionally, the curvy fit was great at butt and thigh, but there was a huge waist gap - enough for both fists to fit in at the lower back.
On a positive note, they are stylish and the material is very nice - soft but not flimsy, and the color was richer, but not darker, than the photo.
