Cosmetic purchases are no longer limited to grooming needs but have become associated with workplace confidence, professional identity, social media visibility, and lifestyle aspirations. This study investigates the financial impact of cosmetic purchases on working women, with special emphasis on monthly budget allocation, savings behaviour, financial stress, and impulse purchase tendencies. A quantitative sur-vey-based methodology is proposed using a structured questionnaire among 250 working women across urban sectors. Statistical tools including descriptive analysis, reliability testing, correlation, regression, and ANOVA are used to examine the relationship between cosmetic spending and personal financial well-being. The findings indicate that frequent cosmetic expenditure significantly reduces discretionary savings and con-tributes to moderate financial stress, especially among younger professionals and middle-income groups. The study contributes to consumer behaviour literature by integrating beauty expenditure with financial decision-making among women professionals.
