Date were provided in a self-administered questionnaire by 200 university women and 166 mothers. The questionnaire included a measure of awareness to underwear items (28 variables) and a social psychological characteristic measure (13 variables). Results obtained are summarized as follows : 1) University women were more interested in the current fashion of the underwears and less concerned about functional or practical aspects of them than were their mothers. 2) Responses to the awareness to underwear items were factor-analyzed separately for the women and their mothers, yielding nine factors : high-grade intention; norm consciousness; taste and preference; and so on. There were significant differences in the scores generated for eight of the nine factors between the women and their mothers. 3) Significant relationships existed in some factors of the awareness and social psychological characteristics.
