How to Begin

First, you'll need to ask someone to assist you in taking more accurate measurements. You'll need a cloth tape measure and a full-size mirror may prove useful. For precise results, you should measure yourself while wearing nearly nothing. A tight T-shirt and underwear will do fine.

Throughout the measuring session, your arms should be well rested at your sides. Remember to keep the measuring tape snug, but not too tight once it's time to record your measurements. Your measurements should be taken in inches, so if it indicates 32 inches, it means you're a size 32.

Find your clothing size:

Take your actual body measurements as they are more accurate than measuring over your clothes.

1. Collar: measure around the base of the neck where the collar sits.
2. Chest: measure the chest at the fullest part, placing the tape close up under the arms making sure the tape is well up at the back over the shoulder blades.
3. Waist: measure the natural waistline just above the top of your hips and below your stomach.
4. Inside Leg: measure from the crotch to where your trouser is normally worn on the shoe.
5. Sleeve: measure from the base of the shoulder down the arm to where you want your sleeve to finish.
6. Outside Leg: measure from the natural waistline to where your trouser is normally worn on the shoe.
7. Jacket Length: measure from the centre back of your neck to your hemline. Then length measurement will vary depending on the style of garment.
