1 Peter 3:1-3

1Wives, in the same way submit yourselves to your own husbands so that, if any of them do not believe the word, they may be won over without words by the behavior of their wives, 2when they see the purity and reverence of your lives. 3Your beauty should not come from outward adornment, such as elaborate hairstyles and the wearing of gold jewelry or fine clothes.
