So I ordered mediums, but received smalls, or at least the black is a small, I haven't checked the white one. It was a happy mistake, because the small fits great! I use the black one with my work pants and I love it. I feel so much more comfortable with my bloated, pregnant tummy. The elastic around the bottom is very secure and doesn't roll up at all. The material is soft and layers well under my loose tops. I leave the button on my jeans undone and then fold down the sides to get a smoother line.

Great product and I'm very happy with it. I feel way more confident with the belly band one then without one and these will keep me from buying maternity clothes for a while.

I wear a size 8 pant for reference.
