Waist Trainer Sweat Belt - Shapewear

Sculpt your waist with a high-waisted 3-strap waist trainer designed for strong, adjustable compression. This style combines a hook-and-eye buckle closure with three wrap-around tightening bands to help you fine-tune support through the waist, lower belly, and midsection. Built-in support stays (keel/boning) help the belt stay upright and reduce rolling, making it great for everyday wear, posture support, or layering under outfits.

Functions (as supplier listed):

Waist support
Shaping / gathering

Fabric name: Polyester
Main fabric composition: Polyester + Spandex blend (for stretch + compression)
Keel / Boning: Yes (support stays for structure and anti-roll support)
Buckle/Closure: Yes (hook-and-eye style closure + adjustable wrap straps)

Feel/Performance:

Smooth, supportive compression with stretch recovery
Structured support from boning to keep the shape stable
Designed to be firm and supportive—not loose like a regular waistband

Fit type: Snug, firm compression with adjustable tightness.

How to choose size:

Measure your natural waist (smallest part of your midsection).
If you’re between sizes, choose:

Size up for more comfort / easier breathing

Size down only if you specifically want stronger compression and don’t mind a tighter feel

How it should feel when worn correctly:

Tight and supportive, but you can still breathe normally and sit comfortably
Sits under-bust to lower belly without folding
Boning stays should feel supportive, not poking
