I want to help you get the best fit with your new waist trainer. Unfortunately these body contouring products do not fit like regular clothing. There is no one size fits all. Every body is shaped differently! That’s why I don’t recommend buying based solely on our size chart. We offer you a free service in which we will get a professional sizing expert to help you determine the best waist trainer and size for you! All you have to do is email us at email@example.com with subject “Sizing Help” and give us your measurements of your waist and torso length as well as a photo of your belly from the front and side view (your face does not have to be included in the photo). We will get back to you within 48 hours from Monday – Friday with a recommended size.
