Become A Kosher Person First

What's the best way to find a kosher wife? Step number one, become a kosher person yourself. Meaning do complete shuva, work on your midot to become the best version of yourself, servant of Hashem. After you do that, the Gemara in Masechet Sota page 2A says that Hakadosh Baruch Hu will give you a wife just like you. If you are a righteous person, he'll give you a righteous woman. If a person is wicked, Hashem will give him a immodest woman. Why immodest and not wicked? Because if she's immodest, certainly she's wicked. But if she's modest, it doesn't mean to say she's righteous. So Hashem says that person that's wicked gets immodest woman.
