1 Peter 3:1

Wives, in the same way, submit yourselves to your husbands, so that even if they refuse to believe the word, they will be won over without words by the behavior of their wives

2 when they see your pure and reverent demeanor.

3 Your beauty should not come from outward adornment, such as braided hair or gold jewelry or fine clothes,

Do read the surrounding verses too, because the context often says more than a single verse.
