Our Size Charts are of ‘Body Measurements’ not garment measurement. To determine what size you fall into ensure to measure against your body. It is best to ask another to help so that you can assume a natural standing position. When using the measuring tape it is important not to pull tight on the tape, the tape should be without tension and sit comfortably agaisnt the body. For a natural measurent one finger should be under the tape, this allows for ‘ease and natural movement’ see Figure.1 below
When we design our clothing we do take into concideration how you will be wearing the garment. For example a winter rainwear jacket you would be wearing insulating layers underneath so the size of the jacket acomidates this. So you wont need to purchace a size up.
