A method for generating safe clothing patterns for a human-like figure is provided. The method includes steps of: a safe clothing-pattern generating device, (a) after acquiring an image of the human-like figure, generating a specific clothing pattern having an initial value, inputting the specific clothing pattern and the image of the human-like figure into a clothing composition network, combining the specific clothing pattern with a clothing of the human-like figure to generate a composite image; (b) inputting the composite image into an image translation network, translating surrounding environment on the composite image to generate a translated image, and inputting the translated image into an object detector to output detection information on the human-like figure; and (c) instructing a 1-st loss layer to calculate losses by referring to the detection information and a GT corresponding to the image of the human-like figure, and updating the initial value by using the losses.
