It's designed to fit a woman with waist measurements up to 44.5 inches. It's made of soft leather for the best in comfort. It's designed for use with a dildo that that has a flared base. Ring size is 1.75 inches in diameter, which fit most dildos from about 1.4 to 2.5 inches in diameter. We recommend the buzz dildo with this harness.
