I think that George and Cindy dress fairly conservatively, they seem like typical, normal people for their age group. They will probably be advised to keep this image and wear their wedding rings. I notice that they hold hands when walking, (which may have been advised to show their relationship strength). I've seen Cindy wear a cross and I've seen Casey wear a demure cross in plain view.
Early on, Cindy was wearing tank tops into the courtroom. George always seemed a bit more conservative.
