I would discourage her from doing it. The Sixth Commandment forbids (ALL) words, looks and actions contrary to Holy Purity the Ninth forbids (ALL) impure thoughts and desires willfully enertained or consented to.
This defenitely comes under the Sixth Commandment since .she would be immodest.
She could cause a lot of men to commit sins of lust and she needs to ask herself that Question. Am I going to cause others to commit sin by doing this.
Any Priest would tell her not to do it.
I dont think it is necessary to get the point across. As a matter of fact it could be a distraction as a lot of people would be looking at her and not get the message that is being put across.
