I ordered these in a medium, because that's the size that I wear in every maternity brand I've worn.  When I got these pants, they were absolutely humongous!  They looked like at least an extra large.  The crotch came to halfway down my thigh, and they were ridiculously long.  Needless to say, I returned them and didn't order another pair.  The stitching is also orange, which I couldn't tell from the picture, and didn't like.
