Take the 3 body measurements as shown below (A, B & C). You may find that your Chest/Bust or Hip are not exactly within one size range – if so, don´t worry. When ordering the lower parts such as pants, tights, take the size best matching with your hip measurement. And when you order the top part: t-shirts, singlets, windstoppers, then select the size that best matches with your Chest/Bust.
