In one aspect, a method for formulating a wearable posture advisory system will be described. A three dimensional body model of at least a part of a body of a user is obtained. A model for 3D printing a wearable posture advisory system is generated based on the 3D body model. The system model models one or more sensors that are arranged to help determine a posture of a user and one or more actuators that are arranged to help instruct the user to adjust his or her posture. The system model is provided to a 3D printer so that the 3D printer can print the wearable posture advisory system. Various embodiments relate to devices, arrangements and executable computer code that are associated with the above method.
