(2) The affected factors of the presenter are dependent on the relations to the presentee and his/her occupation. (3) The affected factors of the store are the floor area and the conditions of locations. 2) Relations between effective factors and purchase amount of each item and relations between purchase motives and each item.

By using items of each group and its sample scores on three axis obtained from quantification theory III, we have found that each axis presented the following characteristics: practicalness, passableness, and liking.
In order to develop an objective evaluation equation of the comfort for women's autumn/winter pajamas, subjective values obtained from a wearing test are regressed with objective values of fabric mechanical parameters, thermal and moisture transport properties, and significant equations for good handle, warm, easy to move, unstuffy, and comfortable pajamas were developped. Subjective evaluations just after wearing pajamas agreed well with those after 5 min lying in Futon. The total comfort of pajamas were evaluated mainly by good handle and easy to move subjectively. Differences among pajamas were small in a relative humidity and temperature in clothing climate, but deviations among panels were large.
