Perfect fit = perfect curves. A critical step to ordering shapewear is identifying the size that will fit your body best. Don’t make the mistake of ordering a size that’s too small because you think you might look thinner. The opposite is true—if it’s too tight, it will be extremely unflattering—and uncomfortable. Follow each garment’s size chart closely; you’ll find it located at the bottom of each product description. Note that some brands’ measurements may vary, so be sure to check the specific waist trainer size chart every time.

For all measurements, use a fabric or vinyl measuring tape and keep it level with the ground. Don’t pull too tight—you should be able to slip a finger underneath the tape.

You might notice that the size chart on our product page differs from the one on the packaging—here’s why.

At MBSWaist, we carefully select and test each shapewear piece for effectiveness, comfort, and fit across diverse body types. Our custom size charts are based on real-world feedback and are tailored to each specific product.

While the general size guide below can serve as a reference, always follow the product-specific size chart on the page when placing your order. It’s your most accurate guide to the perfect fit.
