It was 11:30 am on Sunday morning, and Dorinda Medley was teaching the proper way to gyrate your hips. She would be, unexpectedly, the first of three different Real Housewives stars to lead a gyration tutorial that day. Medley was dressed in metallic spandex pants and a rainbow bejeweled athleisure blazer with her hair stiff in electrified spikes, as if transported from an ’80s jazzercise video, suggesting that she may have had authority on the matter.
