Stand naturally with your arms by your sides. Wrap the measuring tape around the fullest part of your chest, making sure it goes under your arms and across your shoulder blades. Keep the tape horizontal and parallel to the floor. You should be able to fit two fingers between the tape and your chest.

Waist
Stand naturally and wrap the measuring tape around the narrowest part of your waist, roughly halfway between the bottom of your ribcage and your hips. Keep the tape horizontal and parallel to the floor. Avoid pulling it too tight.

Inside Leg
Stand naturally and measure from where your crotch meets your inner leg down to your ankle bone. Keep the tape straight and pulled tight for the most accurate measurement.

Foot Length
Place paper flat on the floor, preferably with one end to the wall. Stand on the paper with your heel touching the wall. Mark the end of the longest toe. Measure from the wall to the mark and compare the measurement against the sizing chart.
