These are gentle-on-the-body and mind fundoshi pants (traditional Japanese loincloth-style underwear) and fundoshi shorts. The fabric area has been widened to provide peace of mind for those with larger posteriors, around an XL size. They can be worn by a wide range of sizes, from M to XL (^-^) Fine silver threads are woven into the fabric, creating a beautiful fabric with an elegant sparkle. If you'd like to know more, please search for "Mufan fabric"♪ (Measured flat) Waist: Approximately 50cm Back width: Approximately 37cm Front width: Approximately 28cm Rise: Approximately 29cm Please note that these are approximate measurements, and there may be slight individual variations. They are made with non-stretch fabric to create a moderate gap between the skin, so although they look quite large, they are less likely to ride up or dig in. Outer: 100% cotton lawn, Mufan Lining: 100% cotton lawn Approximately 80cm of elastic is threaded through and temporarily tied, so please adjust it to your own size. It stretches up to about 100cm. We recommend washing them in a net. Please be aware that dark colors may fade. When drying, please stretch out the wrinkles. I make these with care, but they are handmade by an amateur, so there may be some imperfections in the fabric or seams. Please consider purchasing with this in mind. Please read the profile before purchasing.
