Your leggings should feel secure, comfortable and easy to move in. A few simple checks can help you assess the fit and see how much coverage they provide before wearing them for a workout or everyday activities.
Whether you choose BodyFlexx Waist Trainer Leggings or another style from our Shaping Activewear collection, check the fit while standing, sitting and moving.

1. Check the Waistband
The waistband should sit comfortably at its intended height without digging in, folding over or repeatedly sliding down.
Walk around, sit down and bend forward. If you keep adjusting the waistband, check the size and position of your leggings.
For styles with a hook-and-eye closure, such as our Black Classic Waist Trainer Leggings, choose a setting that feels supportive and lets you sit, bend and breathe comfortably. You don’t need to use the tightest setting.
2. Smooth the Fabric Into Place
Gently work the leggings up from your calves, distributing the fabric evenly over your thighs and hips. The crotch should sit comfortably against your body without hanging low or pulling upward.
Look for:
-
An even fit: The fabric should lie smoothly without excessive bunching.
-
Comfortable seams: Seams should sit naturally without digging in or appearing strained.
-
Freedom to move: You should be able to sit, walk and squat comfortably.
Avoid pulling the leggings into place by tugging hard on the waistband or seams.
3. Do a Coverage Test
Coverage can change when fabric stretches, so check your leggings while moving as well as standing.
-
Try them on with the underwear you plan to wear.
-
Stand in bright, even lighting and check the front and back in a mirror.
-
Squat and bend forward to see how the fabric looks across your hips and seat.
-
Use a second mirror or ask someone you trust to help check the back.
Look for skin or underwear becoming visible through the fabric. Visible underwear outlines are different from transparency—seams can show through even when the fabric itself provides coverage.
4. Check for Overstretching
If the fabric becomes noticeably sheer, seams pull tightly or movement feels restricted, the leggings may be stretched beyond their intended fit.
Open the Size Guide or Size Chart on your chosen product page and compare your current waist and hip measurements. Sizing down for extra compression can affect comfort and coverage.
If the leggings bunch excessively or slide down, you may need a different size or style. Adjusting the fabric into place first can help you tell whether the issue is positioning or fit.
Are BodyFlexx Leggings Squat-Proof?
Check the individual product description for coverage details, as fabrics and construction vary between styles. Fit, fabric stretch, underwear contrast and lighting can all affect how leggings look when you bend or squat.
Even when a style is described as squat-proof, we recommend doing a quick coverage test in your chosen size before your first workout.
Explore our Waist Trainer Leggings to compare styles and review their individual features.
What If I’m Between Sizes?
Use the BodyFlexx Size Guide to compare your waist and hip measurements with the chart for your leggings style, and follow any product-specific fit notes. Don’t automatically choose the smaller size for a tighter feel.
If your waist and hip measurements fall into different sizes, or you’re unsure which fit will work best, contact BodyFlexx Support for help before ordering.
