When buying clothing online, it is not always easy to know which size to choose. To help you make the best choice, SAINT JAMES has developed a size guide tailored to its products.
To find your ideal size, select a garment from your wardrobe of the same type, with a fit and drape that you like, and measure it while laid flat.
