I ordered the exact same pair of these pants in black and loved then so much that I ordered the gray pair. They are smaller and uncomfortable!! Very disappointed the sizing is so different. Pre-pregnancy I am a size 4-6 and ordered these in medium. I would hesitate to try the large since I have small hips and thighs BUT with the stretch waist and adjustable button expansion on both sides, I think I should have gone with the large and the just cinched them smaller. Very disappointed :-(
