How to Measure Your Chest & Arm Length

Wear just an undergarment or nothing at all.

Stand up straight with your arms hanging by your sides and breath normally.

Run a soft tape measure under your arm pits over the largest part of your chest and across your shoulder blades.

The tape measure should be snug, but not tight.

Ask a friend to run a soft tape measure from the centre of the back of your neck, across to the tip of one shoulder, then down the outside of your arm to your wrist bone.

How to Measure Your Waist

Wear just an undergarment or nothing at all.

Stand up straight with your arms hanging by your sides

Breath normally and run a soft tape measure around your waist just about in line with your belly button. The tape measure should be snug, but not tight.

How to Measure Your Inseam

Wear just an undergarment or nothing at all.

Stand up straight with your arms hanging by your sides and your feet shoulder width apart.

Ask someone to help you to measure from your pelvis to the floor
