How to Measure Your Waist

CLEVER® designs hug the body and are tailored with precision. If you’re new to the brand, note that our underwear—including thongs, boxer briefs, and boxers—runs slightly smaller than standard US sizing.

  • Find your natural waist: Wrap a soft measuring tape around your waist, just above your hip bones. Don’t pull tight—stay relaxed.
  • Between sizes? Size up. CLEVER underwear fits close to the body for contour and support.
  • Measure a favorite pair: For extra confidence, compare with a well-fitting underwear at the waistband.

The right fit should support without pinching and highlight your silhouette. Precision never looked (or felt) this good.
