Please note that different styles within the same collection can differ, so using the specific product size guide is important to select your correct sizing.
The size measurements for chest, waist and hips are based on the garments laid flat, unworn, measured horizontally across then multiplied by 2.
To measure the length of a garment, this is a vertical measurement from the top to the bottom.
There is a diagram when you open the Size Chart (see image below).
