If your dress calls for a specific shapewear style—whether it's because your dress has a low back or particular straps—put your best fit forward with SPANXshape™ Suit Your Fancy silhouettes.

How do I know when to size up or down in SPANX shapewear?

First step: find your way to SPANX's Shapewear Size Chart by clicking here.

In general, we recommend sizing up for maximum comfort and an overall confidence boost. (Of note: sizing down doesn't enhance the overall level of compression—it will likely just feel too tight!)

But we get it—fit is personal, and you know your body best. Our Shapewear Size Chart and suggestions can help guide you, but ultimately you know what type and level of compression you want, what style you need depending on what you're wearing, and what will make you feel your absolute best.
