Under the background of the new era,combined with the characteristics of Miao flower belt design in China,the application of virtual simulation and 3D printing technology is conducive to enhancing the artistic expression of Miao flower belt design and improving the development level of costume design in China.However,there are still many problems in the current situation of Miao flower belt design in our country,such as old design concept and single application way.Based on this,Chinese designers should closely follow the needs of contemporary consumers,carry out virtual simulation human modeling,realize virtual simulation of clothing fabrics,innovate the color presentation of flower belts,optimize the expression techniques of flower belts,so as to enhance the design effect of Miao flower belts.
