The sirens are roughly human, but they have 2 fins in place of arms that connect to the sides of the chest, but not to the abdomen. The sirens also do not have pelves or legs, with the body ending at the abdomen, which is a rounded cone-shape. They live in the water, but can obtain metals and fabric, and are as dextrous and intelligent as humans.
Could these sirens cover their chest and the end of their abdomen?
