Disclosed embodiments provide a way to perform body measurements. A garment has a sensor module attached. The garment encompasses a body portion. The sensor module is stretchable and provides electrical data. The electrical data is based on an amount that the sensor module is stretched. The electrical data from the sensor module is collected. The collected electrical data is analyzed to determine a measurement for the body portion. A size for the body portion is calculated, based on the measurement. A second sensor module is attached to the garment. Electrical data from the second sensor is also collected and analyzed. A size for the body portion is further calculated based on the electrical data from the sensor module and the second sensor module. The sensor module and the second sensor module transmit data to a computing device using distinct, wireless transmitters.
