“I’m a boy, and I want to encourage girls to dress more modestly. But how do I do that without appearing rude?” Liahona, September 2015, 59
You’re right to tread carefully in this area. While some young women dress immodestly with the full intent of being immodest, many would be mortified to think someone believed they were dressed immodestly. So be sensitive and consistent. When the general topic of modest dress comes up, enthusiastically support the Lord’s standard of modesty, but don’t condemn individuals. Also, make sure your own personal dress standards and actions are consistent with your beliefs. Young women notice how you dress, and they definitely notice whether you pay more attention to immodestly dressed or modestly dressed young women.
