I bet these idiots discussed this during their Book Reading coffee club.  Got excited and giddy...."Let's DO IT!"  They squealed. Then took days to plan, draw, and design their little costumes.  Invited the "girls" over to help with the sewing (and modeling) of their new creations.  I'm sure they probably danced around the room in the costumes once finished.  Heck, I bet they even flitted around in them for their husbands.   LOL
