The purpose of this study is to better understand the development and characteristics of knit-wear fashion design by examining the transformation process of the modern knits. The subjects of the study are Missoni, Sonia Rvkiel, and Azzedine Alaia, designers who are world-renowned knit designers, and the expressive techniques in their designs will be evaluated The study also intends to analyze the aesthetic value of each designer`s style through their product`s silhouette, colors, and knitting techniques. On the basis of the analysis, we hope to research the factors in the designing process that will allow knits, which were made for practical purposes, to be valued as a luxury fashion item, and with the re-sults, show the potential for knits in expanding its domain in fashion to become a mote luxurious, crea-tive fashion item. The characteristic comparison of the designers is as follows: First, in the case of col-ors, Missoni shows its distinct identity through a balance of splashy colors as well as nature-inspired color composition and balance. And, only with color use, is also able to express perspective, form com-position, and rhythm Sonia Rykiel designs are composed of black backgrounds with strong primary col-ors that are contrasted with one-point or stripes to express a light, urban image. Alaia emphasizes femi- ninity by the use of black and white colors, which show modernity, in combination with neutral skin-ton-ed colors, such as beige and gray So, in other words. Missoni and Sonia, Rykiel mixed colors for visual interconnectivity, while Alaia expressed femininity through the use of an achromatic color. Second. in the case of knitting techniques. Missoni uses the jacquard technique to make complex patterns that show bal-ance of colors and patterns such as zigzag, stripe, geometries, and titan check, which are geometric, ab-stract, and symmetric, Sonia Rykiel who uses stripes as her trademark, most often utilizes the intarsia technique, which is expressed through one-point. Alaia combines diverse techniques, such as the` Skashi weaving, by using computerized knitting. Third, as for silhouettes, Missoni eliminated exaggerated details in order to emphasize the flashy colors and delicate patterns and weavings of its designs, and this re-sulted in simplistic and relaxed silhouettes, Sonia Rykiel took advantage of the elasticity that the knit of-fers to get a tight silhouetten and in turn, emphasized the female sensuality Alaia used curvilinear cuts that emphasized the womanly curves and gained an image considered soft and feminine.
