To improve the aesthetic appeal of pantyhose fabric, a new product was designed and developed and a wear experiment were conducted. We examined the gradational effects of lightness and visual impression of circular plain knitted fabrics made from novel single covered yarn composed of color polyurethane core yarn and uncolored nylon covering yarn with and without dyeing. The results indicate that, in terms of sheerness and gradation of lightness, for pantyhose samples made from single covered yarn, a combination of a coarser color polyurethane core yarn and a finer nylon covering yarn is preferable to that of a finer color polyurethane core yarn and a coarser nylon covering yarn. The gradational effects of lightness on the aesthetic appeal of legs clad in pantyhose are greatly influenced by the size and color of both core and covering yarns in the single covered yarn. Color polyurethane core yarn is useful for improving the distribution of lightness difference between legs with and without the pantyhose fabric on the entire leg wearing pantyhose. It was found that not only the sheerness but also the gradational effects of lightness for three-dimensional appeal of pantyhose is an important aesthetic property in beautifying legs clad in them.

The hypothesis has been offered that mere repeated exposure of novel stimulus object makes a favorable impression. In our three previous studies, we found the mere exposure effect appeared in case of dress. In this study, we study how the mere exposure effect appears in case of colored judo uniform being novel stimulus object, focusing on an aspect of color of dress. We make it clear whether a favorable impression to colored judo uniform is increased by mere repeated exposure of men's and women's colored judo uniform in red, blue and yellow, which colors are changed by an experimental method.
As a result, the mere exposure effect appeared as exposure frequencies approached from 1 time to 10 and 20 times in women's colored judo uniform, but did not appear in case of men's colored judo uniform. In our experiments on both men's and women's colored judo uniform, the mere exposure effect was observed more obviously among female subjects than among male subjects.
