After years of development, clothing design is full of artistic sense, and clothing has developed from traditional clothing to a kind of artistic clothing. The use of Visual Communication (VC) design in clothing design can creatively combine words, symbols, and graphics, but it is difficult to deal with graphics in traditional clothing design. In this article, computer image technology was applied to VC design in clothing design, and the effect of clothing design was improved through the accurate processing of clothing graphics and symbols. This article compared traditional VC design and VC design based on computer image technology in clothing design. The experimental results showed that the average VC effect of traditional VC design and VC design based on computer image technology was 75.98% and 83.72% respectively in life clothing. In fashion clothing, the average VC effect of traditional VC design and VC design based on computer image technology was 76.58% and 85.66% respectively. Therefore, VC design in clothing design using computer image technology can improve the VC effect.
