A discrete wavelet transform (DWT) based generative system for generating images of fashion products is provided. The system includes a memory having computer-readable instructions stored therein. The system includes a processor configured to access a plurality of fashion images of a plurality of fashion products. Each fashion image is generated at a first resolution. The processor is configured to train one or more DWT based generative models using the plurality of fashion images of the fashion products. Each of the generative models is selectively trained using a directional fashion image. The directional fashion image includes details of the fashion products corresponding to a pre-determined orientation and scale. The processor is further configured to generate an upsampled fashion image corresponding to each of the fashion images. Each upsampled fashion image is generated at a second resolution. In addition, the processor is configured to add the details to each of the upsampled fashion images using the directional images to generate target images of the plurality of fashion products.
