They could just have morals. Being scantily clad like this is problematic, and it's especially odd to dress this revealingly when you're out with your husband, regardless of whether or not he's down with it. After all, there are children who watch this event, and even a few who were likely in attendance.

(And yes, I do understand that in secular Western culture there's this general idea that the only thing a women can do wrong sexually is rape, and that regardless of gender, there is absolutely nothing wrong with exposing yourself to as many people as you wish or even whoring yourself out, but I'm a Christian, so I do not care, I'm standing on business.)

But also the dress is freaking ugly. Have you seen it?
