Abstract
This paper examines the seasonal change in the relationship between physical constitution and clothing pressure exerted by the waistband. The subjects were seven healthy women aged from 20 to 47 years. Their weight, waist and other girth measures, waistband pressure measured using a hydrostatic pressure-balanced method, and a sensory evaluation were measured in the summer and winter and compared. In addition, the waistband was fixed at the length that was a perfect fit for each subject and then put around the subject's waist. Weight, bust girth, waist girth, body mass index(BMI), and constructive rate of the waistband for nude length in winter were significantly greater than in summer. As a result, the waistband pressure increased by 3.8 times(a significant 59.3% increase) in the winter compared with the summer(1.18 vs. 0.74 kPa). The seasonal change in waistband pressure was much larger than the change with the phase of the menstrual cycle(15.7% increase). Therefore, when wearing the same clothing year-round, the problem of clothing pressure may arise. Consequently, it is necessary to coordinate the waistband length with the seasonal change in waist girth to eliminate the annual seasonal change in waistband pressure. We discussed the effect of fashions in women's clothes on abdominal pressure and pressure sense.
