To ensure the best fit, it is recommended to take measurements while wearing undergarments similar to those you would wear with the dress. Measure the widest part of the bust for Him width, from the shoulder seam to the wrist for Sleeve Length, around the natural waistline for Waist, and from the highest point of the shoulder to the desired length for Clothes Length. If your measurements fall between sizes, it is advisable to choose the larger size for comfort.
