Buying shapewear for the first time can feel overwhelming. Sizes, compression levels, bodysuits vs. shorts — where do you even start? This guide breaks it down so your first piece is one you actually want to wear.
Start With Where, Not What
The biggest first-timer mistake is shopping by garment instead of by goal. Ask yourself one question: what area do I want to smooth or shape?
- Tummy + waist: a high-waisted brief or shaping bodysuit
- Full torso: a bodysuit or catsuit that works under dresses
- Bust support: a shaping bra or bodysuit with a built-in bra
- Under tight dresses: a thong-back or seamless style with no lines
Browse the full range in our shapewear collection to see which silhouette matches your goal.
Understand Compression Levels
Shapewear comes in light, medium, and firm compression. More is not better — it's about matching the occasion.
- Light smoothing: everyday wear, work, long days. Feels like a gentle hug.
- Medium shaping: the sweet spot for most first-timers — visible smoothing you can wear for hours.
- Firm sculpting: special events, fitted outfits, a few hours at a time.
For a first piece, medium compression is almost always the right call — like our sculpting bodysuits, designed to smooth without squeezing.
Get the Sizing Right (This Is the Whole Game)
Never size down thinking it'll shape more — it won't, it'll just roll, dig, and be miserable. Shapewear works through engineered compression panels, not through being tight everywhere.
Measure your waist, hips, and bust with a soft tape, then check the size chart on the product page. Every Self product page includes a Size Finder that recommends your size from your measurements — takes about 30 seconds.
Between sizes? Size up for all-day comfort, especially in bodysuits.
Pick a Color That Disappears
Black shows under light fabrics. For versatility, start with a shade close to your skin tone — it vanishes under white, pastels, and clingy materials. Keep black for dark outfits.
