Size Guide

How to Measure Your Waist

For the best fit, measure your natural waist β€” the narrowest part of your torso, usually 2–3 cm above your belly button.

Using a soft measuring tape, wrap it around your waist directly against your skin (not over clothing). Keep the tape snug but not tight, and stand naturally without holding your breath.

Tips for the Best Fit

βœ“ Your waist trainer should feel firm and supportive, not painful.
βœ“ You should always be able to breathe comfortably while wearing it.
βœ“ If you’re new to waist training, start with 1–2 hours per day and gradually increase wear time.
βœ“ Always measure before ordering, as sizing may vary between styles.
