The use of hidden bathing patches among desi girls can be attributed to various factors. In some communities, there's a strong taboo around women's bodies, particularly during menstruation. The notion that a woman's body is "impure" or "polluted" during this time leads to strict restrictions on her mobility, social interactions, and even bathing. The patch serves as a means to conceal the genital area, thereby maintaining a semblance of modesty and purity.
