A belly cast is a three-dimensional plaster sculpture of a woman's pregnant abdomen as a keepsake of her pregnancy. It can also be known as a belly mask, pregnancy belly cast, a pregnant plaster cast, or prenatal cast. Belly casts are most often made toward the end of the third trimester of pregnancy, though a series of casts may also be made during the pregnancy. They are made by preparing the skin with a coating of a lubricant and adding strips of wet plaster gauze over the abdomen to make the cast. Some women also cast their breasts, arms, hands and thighs into a full torso sculpture.
