These  are so comfy! I was skeptical of the one size fits all because I'm not very big. I'm 5'1" with very short legs, even for my height. Currently 23 weeks pregnant and about 140lbs at the moment. These pants fit amazing! They are a tiny bit long and bunch just a bit around the ankles, but that's normal for me. They feel like a mix between sweatpants and leggings. They are pretty stretchy, and have an internal stretchy drawstring in the top of the belly part, so I think I'll just live in these for the rest of my pregnancy!
