It's a kind of JW uniform. Not surprising because what they really want is Uniformity not Unity as they say.
So we have this change of dress and grooming standards now with the relaxation of beards.
Maybe someone finally told them that they weren't looking like upstanding members of society anymore, they were looking like JWs! It's easy to pick them out of a crowd.
So, what do they want? To blend in as respectable citizens or look different? They need to decide because the loose polyester suit and long skirt/ cardigan is making them stand out. No one dresses that way anymore.
