The application of metaverse technology in the retail is often seen in the form of digital human, virtual store, virtual experience, virtual production, digital collection, etc., integrating online and offline interactive or only serving the virtual world. The retail metaverse has been initially established in the beauty makeup, garment industry, home decoration and automobile retail. There are some unique problems in the retail metaverse, such as new economic risks, increasing technological costs and barriers to user acceptance. The reasons for these problems lie in the imperfection of legal rules, the immaturity of technology development and the lack of individual coping ability. We need to improve laws and regulations, support the digital transformation of the retail and provide responsible public management services at the government level, develop advanced technologies and adhere to technology for the good at the enterprise level, and enhance digital ability and rational resolution at the individual level.
