Why the Right Size Matters

Shapewear that’s too small can feel restrictive, while shapewear that’s too large won’t deliver the smoothing and support you’re looking for. The right size ensures that your SPANX:

• Smooths and sculpts comfortably without digging in.
• Moves with your body so you can wear it all day.
• Delivers the right compression to achieve your desired look.

That’s why we’ve created an easy-to-follow size guide with measurements you can trust. Whether you’re shopping for bodysuits, shorts, or shaping leggings, our guide takes out the guesswork.

How to Find Your Perfect SPANX Size

1. Grab your measurements. Use a soft tape measure around your bust, waist, and hips.
2. Check the size chart. Match your measurements to our size guide for the best fit.
3. Choose your true size. Don’t size down for “extra” shaping—our designs are engineered to deliver smoothing power without compromising comfort.

Pro tip: If you’re between sizes, consider the compression level you prefer. A higher level will feel firmer, while a lower level will give you a more natural feel.

Understanding SPANX Compression Levels

Every body is different, and every outfit calls for a different type of smoothing. That’s why SPANX offers five levels of compression, from light support to maximum sculpting power:

1. SPANXsmooth™: Just a light touch. Think of it as a gentle hug that smooths without shaping—perfect for layering or lounging.
2. SPANXsupersmooth™: Easygoing and ultra-soft, this level gives you everyday comfort with light contouring that feels barely there.
3. SPANXshape™: A happy medium. It hugs in the right places to enhance your natural curves—great for when you want polish without pressure.
4. SPANXsculpt™: More support, more confidence. This one firms and smooths your core for a sleek silhouette that still lets you move.
5. SPANXsupersculpt™: Your go-to for max shaping. Designed for big moments when you want everything held, lifted, and on point—from wedding days to wow moments.

Think of it as a spectrum: from “barely-there smoothing” to “red-carpet ready.” You get to choose how much shaping power feels right for you.

Frequently Asked Questions About SPANX Shapewear

Should I size up or down in SPANX shapewear?

Always go with your true size based on your measurements. Sizing down may feel overly tight and uncomfortable, while sizing up can reduce the shaping effect. Our size guide is the best place to start.

How do I know what compression level is right for me?

Consider the occasion and how much shaping you want. For everyday wear, Level 1–2 is great. For special events or form-fitting outfits, Levels 3–5 will give you more sculpting power.

Do different SPANX styles fit differently?

Yes! Bodysuits, shorts, and leggings all have unique fits. That’s why we recommend checking the size chart for each style before purchasing.

Can shapewear be comfortable all day?

Absolutely. SPANX designs are made with comfort in mind. Choosing the right size and compression level ensures that your shapewear feels supportive—not restrictive—even during long wear.

What if I’m between sizes?

If you’re between sizes, think about your preferred compression level. If you like a snugger, sculpted feel, go with the smaller size. If you prefer more comfort and flexibility, the larger size may be best.

Why does my shapewear roll down or up?

Shapewear can sometimes roll if it’s not the right size, if the compression level doesn’t match your body type, or if it’s being worn with fabrics that create extra friction. High-waisted pieces, for example, may roll down if the waist measurement is too small, while shorts may roll up if the leg opening is too tight.

How can I prevent my shapewear from rolling?

Here are a few tips to keep your shapewear smooth and in place:

• Choose the right size. Rolling often means the garment is too small. Always check our size guide before buying.
• Match the style to your outfit. High-waisted shapewear works best under dresses or pants with a natural waistline, while bodysuits can help prevent rolling at the midsection.
• Look for features that grip. Many SPANX styles include silicone grip strips or design details that help keep shapewear in place.
• Avoid lotion or oils before wearing. These can reduce grip and make the garment more likely to slip.

How do I care for and wash my SPANX shapewear?

To keep your shapewear looking and performing its best, hand wash in cold water with a gentle detergent, then lay flat to dry. Avoid bleach, fabric softeners, and the dryer, as they can damage the fibers and reduce elasticity. With proper care, your SPANX will stay supportive and comfortable wear after wear.

The Bottom Line: Confidence Starts with the Right Fit

Finding your perfect SPANX shapewear size doesn’t have to feel overwhelming. With our easy-to-use size guide and clear compression levels, you can choose pieces that not only smooth and sculpt but also feel effortless to wear all day. By selecting the right size and level of support, your SPANX will move with you, boost your confidence, and help every outfit look its best.
