In our present aging society, a large number of problems need resolved so that clothing designed for the elderly allows them to enjoy an independent life. Considerable progress has been made in research and development of supportive welfare devices and barrier-free homes, but little has been done to solve the problems associated with ready-made nightwear, such as the limited number of sizes, inappropriate sleeve and trouser lengths and crotch depth, and lack of pockets. In the present study, we therefore conducted market research and a questionnaire survey, and based on the results, made three pairs of pajamas considered acceptable for elderly women. An additional pair was also made taking into consideration the most common grievance items. The visual appearance and fit of a total of 6 pajamas, the above and 2 ready-made pajamas made of different material and with different button features, were evaluated. Our evaluation produced the following results :

1. Cotton fabric with a light colored floral pattern was most appropriate.
2. Pajama tops with buttons on the front, no collar and an adequately long body, short raglan, elasticated sleeves, and bilateral pockets were preferred.
3. Pajamas trousers with a short inner leg and unnelasticated hems, and pockets to identify the front from the rear were preferred,
4. The collar, which often appears cramped in ready-made pajamas, should be widened.
The results indicated that a slight difference in length and width affected the comfort of pajamas, Taking this into consideration, appropriately designed pajamas should be made available.
