The most ideal way to pick the right size garment is to take a shirt that fits you well right now and lay it down on a flat surface. Measure the width from underarm to underarm and the height in centimeters per the model defined here. Match those measurements up with the charts below and you’ve got your size. If the size measurements are just above the size category then we recommend increasing the size category up to the next level. Some items and colour ranges also stock 3XL, 4XL, 5XL. Please note these have a sizing surcharge imposed by the manufacturer.
