I Peter 3:3-6

³Your adornment must not be merely external—braiding the hair, and wearing gold jewelry, or putting on dresses; ⁴but let it be the hidden person of the heart, with the imperishable quality of a gentle and quiet spirit, which is precious in the sight of God. ⁵For in this way in former times the holy women also, who hoped in God, used to adorn themselves, being submissive to their own husbands; ⁶just as Sarah obeyed Abraham, calling him lord, and you have become her children if you do what is right without being frightened by any fear.
