Size Guide

Use your body measurements to find your recommended Gigo size. Measurements in inches are shown first, with centimeters included as an additional reference.

Body measurements, not garment measurements

How to Measure

Use a soft measuring tape and measure directly against your body. Stand naturally, keep the tape level and make sure it feels comfortably fitted without pulling it tight.

Keep the measuring tape parallel to the floor and comfortably fitted against your body.

Waist Measurement

Wrap the measuring tape around the area where you normally wear the waistband of your underwear, swimwear, shorts or pants. This is typically just above the hip bones. Keep the tape parallel to the floor and do not pull it too tightly.

Chest Measurement

Wrap the measuring tape around the fullest part of your chest, directly under your arms. Keep your arms relaxed and make sure the tape remains level across your back.
