Abstract: Virtual clothing is a virtual reality application based on computer technology. Its background and purpose are to provide people with a new fashion experience. With the rapid development of virtual reality technology, virtual clothing has begun to show more and more application scenarios, such as virtual fitting and metaverse. Virtual clothing can not only provide consumers with a better shopping experience, but also reduce the cost of the brand and reduce environmental pollution. Therefore, there are great potential and development space for the research and application of virtual clothing .
The research of virtual clothing began in the 1980s. Early studies mainly focused on physical simulation technology of cloth. For example, in 1986, WEIL proposed a method based on cloth synthesis. Subsequently, TERZOPOULOS et al. extended it to elastic deformation and inelastic deformation, such as the elastic deformation model proposed in 1987 and the inelastic deformation model concerning viscoelasticity, plasticity and fracture proposed in 1988. Researchers are committed to improving the realism and fidelity of virtual clothing, and effectively reducing the amount of calculation and simulation complexity. 
With the continuous advancement of technology, the research of virtual clothing has gradually shifted to application. Aiming at the bottleneck problem of virtual fitting, many studies have focused on optimizing the fitting process. For example, KOO et al. proposed the problem of semi-drag skirt cutting angle in 2009, while WANG and LIU developed a virtual fitting platform based on CLO3D in 2020.
In the context of the metaverse, the research of virtual fashion is increasingly focused on the integration of cutting-edge technologies such as artificial intelligence and blockchain, like artificial intelligence-based textile feature modeling, and probability distribution model of virtual try-on experience. In addition, with the development of blockchain technology, the application of non-homogeneous tokens (NFT) in the field of virtual fashion has also begun to receive attention. For the display of virtual fashion, virtual try-on systems based on technologies such as augmented reality (AR) and virtual reality (VR) in existing research have broad application prospects.
Virtual clothing is always committed to providing a new fashion experience. In the past few decades, researchers have made a lot of progress from physical simulation to the application of metaverse. In the future, virtual clothing will continue to grow and develop, and will be applied in more markets and application scenarios. At the same time, the emergence of various emerging technologies will also bring new opportunities and challenges to the development of virtual clothing. Therefore, researchers need to continue to pay attention to the development trends and needs of the virtual clothing field, and propose more innovative solutions to promote the rapid development of virtual clothing technology.
