Some people buy luxury goods with interest, while others use their capital from part-time jobs. Forcing young girls to invest their limited capital in luxury goods and extravagant indulgences deprives them of the possibility of a truly better life, imparts misguided values, and uses distorted perspectives to lead more young girls down a crooked path. This is an evil act.

A focus on fashion will never lead you to shore.
