Which SPANX underwear are best for shaping your belly?

For everyday shaping, try SPANXshape™ ExtraOrdinary. Though technically shapewear, these styles are lightweight, comfortable, and the perfect level of shaping for everyday wear. 

Looking for more tummy control? Try our SPANXsculpt™ OnCore shapewear—it’s a favorite for a reason (or several). Lightweight and powerful. Strong support and firm compression. Bonded sculpting panels for your tummy. So many benefits in just one style!

Which SPANX underwear best shapes your body?

Everybody, and every body, is different—each with their own preferred style and preferences. We know that you know what underwear styles you like best, and we’re here to help provide you shaping options in the silhouettes you love. Here are some of our favorite options:

For 360-degree shaping, we’d recommend our SPANXshape™ Invisible styles—equally as shaping as they are undetectable, they are super comfortable for daily shaping, making them a perfect alternative to traditional underwear. 

If you’re looking for a little lift in the back, our SPANXshape™ Booty-Lifting brief and mid-thigh short do just that—giving your booty the lift and support it deserves.

Does SPANX carry underwear with invisible panty lines?

We do! Pick from two collections: SPANXsmooth™ Undie-tectable or SPANX Fit-to-You underwear packs. Both provide ultimate comfort, and neither give you those pesky panty lines. The difference? Undie-tectable has built-in smoothing while Fit-to-You is non-shaping.
