HOW TO MEASURE
CHEST : Take the tape measure and wrap it around the widest part of your chest. Keep the tape measure straight and level at back and parallel to ground.
COLLAR : Measure around the fullest part of your neck where a shirt collar would sit. Ensure the tape measure is level all the way round and take the measurement with your index finger underneath the tape. This will ensure your collar is a comfortable fit, and not too tight.
WAIST : Measure around your natural waistline, which is the narrowest part of your waist. Measure approx. 6cm under your belly button
INSEAM : Measure from the crotch seam to the bottom of the leg.
