Take your measurements over your basic undergarments normally worn. Stand erect without shoes with your feet shoulder width apart. For circumference measurements, make sure to keep the tape measure parallel to the floor. Determine your measurements following the directions below.

CHEST – With arms down, measure around the fullest part of your chest.

WAIST – Measure around the narrowest part of your torso.

HIP/SEAT – Measure around the fullest point of your hip/seat.

THIGH – Measure around your thigh, 1″ below crotch. Thighs often differ between legs; measure both and use larger measurement.

INSEAM – Measure from crotch point to the floor. Make sure you are standing with your weight balanced and posture straight.

Tips for Accurate Measurement:

  • For best accuracy, have someone else take your measurements.
  • Take your measurements over the undergarments you typically wear.
  • Stand straight but relaxed, with feet placed shoulder width apart.
  • Take measurements barefoot or in socks.
  • Use a flexible cloth measuring tape.
  • Make sure the measuring tape is parallel to the floor when you take your measurements.
  • When taking inseam measurements, stand straight and look straight ahead. If you look down at your feet, the measurement may come in shorter than it should!

All measurements are in inches. The measurements provided refer to body size, not to garment dimensions. Size up if you are between measurements – or size down if you prefer a tighter fit. Refer to the Measurement Guide for instructions on how to find your measurements.
