Measuring advice

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.

(3) Waist:

measure the natural waistline.

(4) Inside Leg:

measure from the crotch to where your trouser is normally worn on the shoe.

(5) Body Length

To determine jacket length requirements, measure from the centre back of your neck line to the natural hemline. Check size guide to establish if a Short, Medium, Long or Extra Long length is required. Jacket lengths vary depending on the style or the fit of the garment.
