In reference too “wearing a lot of make-up in public is not tsnius for a married woman.” Waiting for the valet after a chasuna I commented to my wife about a woman standing a few feet away from us who was wearing way too much makeup. I said something to the effect of, if she smiles any wider, whole sections of her face will crack off. Unfortunately, I said it a bit too loud and she heard. She pulled my wife to the side and (my wife reports) proceeded to wipe away makeup from a section of her face revealing a large welt.
