Abstract: A method for optimizing individually tailored garments includes measuring at least one body part and generating a first data set for manufacturing the garment, including measured data, manufacturing the garment based on the data, the garment including a passive indicator element via which properties and/or changes of the garment due to wear is determined, and use of the first garment. The method includes examining the first garment regarding changes due to wear for producing a second similar garment, thereby generating a second data set containing measured data of the first garment, comparing the second and first data sets, and checking the passive indicator element with regard to information relevant to producing the second garment. Then, a third data set based on the first and second data sets, and the result from the passive indicator element check is generated, and the second garment is manufactured based on the third data set.
