Ideally, they would have a different dress and bearing than the average worldling.
Perhaps they would be seen in a Catholic-friendly locale rather than a movie theater.
Traditional Catholic women should be seen always with modest skirts/dresses and never wear pants in public. Men shouldn't wear anything immodest either -- and modest presumes no vulgar or worldly slogans on your shirt. A temple of the Holy Ghost should not be a walking billboard for a large corporation -- unless you're being paid well for it. :wink:
When I see a large family, especially with all the girls not wearing pants, I always take notice. Of course, I always tell myself "they're probably Mormon" because so few Catholics, even Traditional ones, take their Faith out into the streets.
Not that every traditional Catholic is malicious, but I think many of them simply don't know how to properly resist the world. They have no idea just how far the world's standards are from what is objectively good.
