How to advise a sister that show her beauty ? (Dawah between sisters)

How should the Muslim woman that is daa'iyah ( sister that call to Islam) to advise Muslim women who show their beauty?
"....She advises, telling her sisters in Islam "You must avoid meddle with men. you must avoid going uncovered , and you must be diligent in taking proper head cover when you meet men in front ,of which is not permissible to be exposed in front of them.
Allah The All-mighty says:

"When you ask them an object do it from behind a curtain. It is purer for your hearts and for theirs" (Al-Ahzaab: 53)

And the Most-High also says:

" And do not display their beauty except in the presence of their husbands" (An-Nur:31)

So She brings the verses and narrations that are appropriate and contain the clarification of what Allah has commanded. Also warns what is opposed to the legislation pure and clear to their sisters in Islam which is mandatory  for all of us, while warning of what  Allah has forbbiden.

And we must cooperate in righteousness and piety and the defense of truth ,  persevering patiently."
