These are fundoshi pants, or fundoshi shorts, gentle on both body and mind. We've made the fabric area wider to ensure comfort even for those with larger hips, around an XL size. They can be worn by a wide range of sizes, from approximately M to XL (^-^) The Miracle Wave fabric is a soft, textured material that is gentle on the skin ♪ (Measured flat) Waist circumference: Approximately 50cm Back width: Approximately 35cm Front width: Approximately 26cm Rise: Approximately 29cm Please note that these are approximate measurements, and there may be slight individual variations. The non-stretch fabric is designed to create a slight gap between the fabric and your skin, so while they may look quite large, they are less likely to ride up or dig in. Outer fabric: 100% Cotton Lawn, Miracle Wave Lining fabric: 100% Cotton Broadcloth (slightly thin) Approximately 80cm of elastic is threaded through and loosely tied, so please adjust it to your own size. It can stretch up to about 100cm. The waistband has three elastic bands, which should provide a stable and comfortable fit. For your reference, if you find them too tight, removing the bottom elastic band will give you a feeling of looseness, as if you've gone up a size. We recommend washing them in a laundry net. Please be aware that dark colors may fade. We put our best effort into making these as handmade items by an amateur. Therefore, there may be slight distortions in the fabric or stitching. We ask for your understanding before considering a purchase. Please read our profile.
