I read somewhere that it was a mortal sin to tempt men, but venial to dress out of vanity, to show off wealth, and so on.
I just figured that if the mortal sin is to dress to INFLAME MEN, then it would be venial to dress to make other women jealous or to show off -- such was my deduction. Of course I realize that just dressing to look nice at Church is not a venial sin, there has to be an element of ostentation to it.
If I'm wrong, please correct me. Moral theology isn't my field so much as plots and cօռspιʀαcιҽs. If they somehow impinge on moral theology, then I get interested...
