Each product has its own unique size guide located on the product page. We cannot guarantee at 100% that the size will work for you however, we do have a 98% accuracy when using our size guides.


Our shapewear is designed to be true to size, and we understand the importance of finding the perfect fit. To assist you in selecting the right size, we have a comprehensive size guide available on each product page. This guide provides accurate measurements to help you determine the most suitable size for your body.

Please Note:

These size charts are true to size and are based on body measurements. Due to the nature of the materials, we do not recommend sizing down. If you are between sizes or at the higher range of the chart, we recommend selecting the larger size.
