I have three of these now, one in the g string and two full bottom ones. I started with a 2x, waist is 42, but realized it was not doing much as it was too easy to put on lol. I bought this style in a 1x. It does hold in more, but its not a tight cinched type hold, more like a tight stretchy tank top hold. It think someone with less of a tummy could benefit from this.
