no, wasn't a similar hoohaw a few years ago, with a swimsuit with alternative rough smooths lines down the body to direct the flow of water, maybe the corsetting effect is more of change, but many sports have brace like things for their athletes, like weightlifting, most shoes... emmm, the amount of strapping they put on themselves alone starts to allow to do thing that most people can't
you can see on the suit the... low-drag panels in points where water flow is greatest.
