Abstract

The study aims to identify the illusive design that can be effectively implemented on apparel to accommodate individuals with varying body proportions. In addition to the implementation of illusive designs on apparel, the study also delves into the concept of fashion illusion from a cognitive science perspective. According to the study, it is suggested that the golden ratio (1.618) is the ideal number for accurately perceiving dresses without any optical illusions. A structured questionnaire was developed to determine the effect of the golden ratio on creating a fine-looking or illusive appearance, as illusion is sometimes preferable for different nonstandard body shapes. Furthermore, this study recommends that illusion in fashion should be considered a physical state rather than a so-called mental state, aligning with cognitive science. It asserts that the concept of “illusion” itself does not truly exist.
