This research work was carried out to assess the influence of female university undergraduate‟ moral standard on dress code implementation in North-West Nigeria. The objective of this research is to examine the influence of female undergraduates‟ age, marital status, moral value and sexual morality on dress code implementation. The study was conducted using descriptive survey design with the target population of seventeen thousand, one hundred and sixteen (17,116) female undergraduates. A sample size of three hundred and seventy-five (375) was obtained. The instrument used for data collection was questionnaire. Demographic information was analyzed using frequencies and percentages. Four research questions were analyzed using means and standard deviations. Regression analysis was employed in testing the four null hypothesis at 0.5 alpha level of significant. Findings revealed that dress code implementation in universities in North-West Nigeria has significant influence on female undergraduates‟ age, marital status, moral value and sexual morality.

Based on the findings, the researcher recommended among other things that university authorities should intensify awareness campaign on the importance of abiding by the stipulated dress code. In addition, booklet containing rules and regulation guiding dress code should be made available to all students.
