Following the examination of optical illusion patterns on a flat surface that we conducted in the first year, we now chose to study optical illusion patterns in three dimensions. More specifically, simulation models of four body types were created on a design creation system, whereupon the characteristics of each body type were identified. These were then used as the basis for the design and creation of one-piece dresses with optical illusion patterns that would compensate for each body type, whereupon their effects were examined and a pattern was selected that appeared effective. Using an ink-jet printer, the selected pattern was printed on polyester fabric, and experimental one- piece dresses was made. The experimental one-piece dresses were mounted on dressmaker's models against a white background, and female monitors (n=22) were asked to make visual assessments of the optical illusion effect. Our results indicated that even the same pattern gives body types a different look depending on such factors as pattern size, layout, and direction. In particular, the continuous arrangement of the pattern from the chest to the waistline had more effect when it forms a curve than when it forms an angle.
