Women who are single should exhibit these qualities. Their reference must confirm this in their reference letter/email.

1 Peter 3:3-4

3 Your adornment must not be merely external—braiding the hair, and wearing gold jewelry, or putting on dresses; 4 but 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."

1 Timothy 2:9-12

9 Likewise, I want women to adorn themselves with proper clothing, [d]modestly and discreetly, not with braided hair and gold or pearls or costly garments, 10 but rather by means of good works, as is proper for women making a claim to godliness. 11 A woman must quietly receive instruction with entire submissiveness. 12 But I do not allow a woman to teach or exercise authority over a man, but to remain quiet.
