I bought a small and medium size. The small fits me now with a bit more support than the medium. The medium will be great in another month or two. I am 182lbs 6mo pregnant (165 pre-pregnancy) I have athletic, legs and the small is just large enough not to make an indentation or squeeze the fat, but it's borderline. I am pretty much all stomach in my pregnancy though, so consider size if you carry differently. This is the perfect product, and I've bought a few. It smooths out and lifts the stomach, and gives a nice support, but it's not too firm like spanks (which I've tried and it was very uncomfortable pregnant). The top of the band does NOT cut into your skin; it's soft and stretchy but also does not fall. I fully recommend this product.
